x 4
Transfered data
Data transfered from CASU shall consist of processed pixels (where the processing steps are specified by the observing protocol used), confidence maps, derived source catalogues and associated description data; no raw pixel data will be transfered to (or held in) the archives. Where irreversible stages such as stacking or mosaicing have been done as part of the reduction procedure, the individual component images and catalogues shall be transferred also. Library calibration frames shall be transfered (e.g. dark frames, flat fields, master skies) for use by users (not for any processing at the archive end).
TOP-LEVEL DATA SPECIFICATION
Preliminaries
Processed frames shall be stored in FITS format, following the guidelines set out in [1]:
- the images comprising a multi-device image frame shall be stored in different image extensions of the same FITS container file (a multi-extension FITS, or MEF, file); data pixels belonging to one chip's image shall be stored in one image extension (guideline-2);
- the primary data array in the MEF file shall be empty (guideline-3);
- keywords describing the dataset in the MEF file as a whole shall be written into the primary HDU, keyword INHERIT set to T to indicate this and extension-specific metadata written into the corresponding HDU (guideline-5)
- single mosaic image products may be written in standard FITS primary HDU files OR in MEF files with one extension, depending on the application code that generates them.
Derived source catalogues corresponding to each image extension shall be written as FITS binary tables in extensions of a single, separate MEF file with a similarly empty primary array. The headers for the catalogue MEF shall contain all the information of image MEF headers plus ancillary processing keywords and values.
General FITS keywords
Keywords shall follow the standards set out in [1] and [6] and as described in [3] (for WFCAM data) and [15] (for VISTA). Keywords and associated values written to the HDS container files produced by the WFCAM DAS must, where appropriate, be propagated through the JAC/CASU interface, through the data processing pipeline and into the science archive. Similarly, VISTA camera DAS metadata must be propagated through the data flow system.
The first keyword in any extension HDU must be XTENSION, and it's value
shall take on only 'IMAGE ' or 'BINTABLE';
the EXTNAME keyword is
used to identify the extension with a particular device detector and a unique
ID for each device used in the respective infrared cameras must be propagated
through the data flow via an assigned keyword. Binary
tables shall have every column described by keywords TTYPEn,
TFORMn and TUNITn (see later).
World Co-ordinate System (WCS; ie. astrometric) information shall be propagated using a set of standard keywords described in the latest FITS WCS standards [11,12] by Greisen and Calabretta.
Pipeline data products must pass NOFS FITS verification (via checks employing
fverify) to be acceptable to the archive.
Physical units
Physical units shall comply with SI units and their derivatives with a few exceptions for astronomical convenience (see [1] Section 9, Table 14).
Celestial co-ordinates shall be expressed in a system described by
primary HDU keyword RADESYS; it is anticipated that this will have
ICRS (i.e. Hipparcos/Tycho) over the
lifetime of WFCAM, but this may of course change for VISTA. The keyword
EQUINOX shall be included for backwards compatibility to explicitly
give an equinox for older software (note that raw VISTA data is expected
to use FK5 until the whole VLT system is brought into line with IAU 1997).
File naming conventions
For WFCAM, CASU/JAC/ATC have an agreed policy on filenames; furthermore, it is UKIRT policy to use run numbers that reset back to 1 each night. For ease of tracking files through the data flow system, the CASU/WFAU interface follows the same policy, with conventions for processed products, as follows:
- at the telescope, the DAS produces files called
wayyyymmdd_12345.sdf,wbyyyymmdd_12345.sdfand so on, where the a,b,c,d correspond to detector, w stands for wfcam and12345is the 5 digit run number; - CASU shall create 2D raw MEF files from the individual NDFs as a precursor
to input to the processing pipeline front-end, with names of the form
wyyyymmdd_nnnnn.fitand processed filenames of the formwyyyymmdd_nnnnn_suffix.fitwhereyyyymmddis the UT date of observation,nnnnnis the UKIRT DAS running number (reset to 1 on a nightly basis) and_suffixis a combination of an underscore character plus two-letter abbreviations indicating pipeline processing actions:_sf= interleaved superframe,_st= stack,_sf_st= stacked superframe,_sf_tl= tiled superframe etc. Catalogues generated from frames shall berootname_cat.fitsand confidence maps for framesrootname_conf.fit, etc.
For VISTA, the file naming convention shall be similar.
Convention for null values
The ANSI/IEEE-754 floating-point number standard defines certain special
values that are used to represent such quantities as
not-a-number (NaN), denormalized, underflow, overflow, and infinity (see
the Appendix in the NOST FITS standard [6] or the NOST FITS
User's Guide for a list of these values). The
CFITSIO routines that read
floating point data in FITS files recognize these IEEE special values
and by default interpret the overflow and infinity values as being
equivalent to a NaN, and convert the underflow and denormalized values
into zeros. In cases where programmers may want access to the raw IEEE values
without any modification by CFITSIO, this can be done by
calling the fits_read_img or fits_read_col
routines while specifying 0.0
as the value of the NULLVAL parameter. This will force
CFITSIO to
simply pass the IEEE values through to the application program without any
modification.
Since most of the binary
tables contain floating point numbers there is no need to specify null values
as these can be specified transparently in CFITSIO.
Null floats shall be
set to FLOATNULLVAL (equivalent to IEEE not-a-number) and
the CFITSIO routines used as normal. For any
integer columns, the FITS null value shall be explicitly
defined by the TNULLn keyword.
DETAILED DATA SPECIFICATION: WFCAM
Data obtained at the time of observation
Observations shall be described via the keywords OBSERVER,
USERID, OBSREF,
PROJECT, MSBID, OBJECT,
SURVEY and SURVEY_I keywords.
Instrumental characteristics, set-ups and parameters shall be described by
keywords as detailed in [3],
including instrument detector configuration
(e.g. array used DETECTOR; number of integrations NINT),
detector controller information (e.g. camera read mode READMODE;
read-out application
CAPPLICN), optical configuration (e.g. filter name FILTER;
base focus position FOC_MM) and observing conditions/environment
(e.g. air temperature
AIRTEMP; relative humidity HUMIDITY; opacity data CSOTAU).
All these FITS keys will be propagated through the data flow chain from the
DAS to the WFCAM Science Archive (WSA).
Data products
Corrected pixel data
The CASU pipeline corrects WFCAM pixels into a
product that is instrument-signature free. The
reduction steps involved in doing so, the derived astrometric and
(first-cut) photometric calibrations and resulting DQC information
generated shall be propagated into the WSA using FITS keys
detailed in the appendices in Section 9.
Appendix 9.1 shows example
FITS keys for the primary HDU; Appendix 9.2 shows an example of
an extension set.
Differences in the FITS keys in primary extension HDUs for combined frame
products shall be limited to the propagation of provenance information,
i.e. a list of the individual frames that have been combined in the pipeline
to create a combined frame product will be listed as a set of PROVnnn
keywords.
Library calibration frames shall have identical FITS keys to science frames,
but library frame keywords for library frames will not refer to other
frames (e.g. library flatfields will not be flatfielded, etc).
Pixel data values shall be represented in 4-byte integer numbers
(i.e. BITPIX=+32) and CFITSIO `Rice' tile compression [14]
shall be employed to facilitate efficient storage and network transfer.
Whenever possible, all processing will maintain the original units,
i.e. if the original raw data run from 0 to 100,000 ADU, the range in data
numbers in processed frames will be similar. At this stage, we allow for
the posisbility of use of BSCALE and BZERO FITS keywords
and values to recast 4-byte integers into floating point numbers.
Source catalogues
The standard set of CASU source detection parameters can be found
in [5].
An example FITS header for a catalogue MEF is given in Appendix 9.3.
The following are an extract of the corresponding FITS binary table details for
each catalogue attribute (TFORM is 1E throughout):
No. Name TTYPE TUNIT 1 Seq. no. Sequence_number - 2 Isophotal flux Isophotal_flux ADU 3 X co-ordinate X_coordinate pixels 4 Error in X X_coordinate_error pixels 5 Y co-ordinate Y_coordinate pixels 6 Error in Y Y_coordinate_error pixels 7 Gaussian sigma Gaussian_sigma pixels 8 Ellipticity Ellipticity - 9 Position angle Position_angle degrees 10 Areal profile 1 Areal_1_profile pixels . . 17 Areal profile 8 Areal_8_profile pixels 18 Peak height Peak_height ADU 19 Peak height error Peak_height_error ADU 20 Aperture flux 1 Aperture_flux_1 ADU 21 Aperture flux 1 error Aperture_flux_1_error ADU 22 Aperture flux 2 Aperture_flux_2 ADU 23 Aperture flux 2 error Aperture_flux_2_error ADU . . 44 Aperture flux 13 Aperture_flux_13 ADU 45 Aperture flux 13 error Aperture_flux_13_error ADU 46 Petrosian radius Petrosian_radius pixels 47 Kron radius Kron_radius pixels 48 Hall radius Hall_radius pixels 49 Petrosian flux Petrosian_flux ADU 50 Petrosian flux error Petrosian_flux_error ADU 51 Kron flux Kron_flux ADU 52 Kron flux error Kron_flux_error ADU 53 Hall flux Hall_flux ADU 54 Hall flux error Hall_flux_error ADU 55 Error bit flag Error_bit_flag flag 56 Sky level Sky_level ADU 57 Sky variance Sky_variance ADU 58 Child/parent Parent_or_child_flag flag 59 Right Ascension RA radians 60 Declination DEC radians 61 Classification Classification flag 62 Profile statistic Class_statistic N-sigma 63 PSF flux PSF_flux ADU 64 PSF flux error PSF_flux_error ADU 65 PSF fitted X PSF_fit_X pixels 66 PSF fitted X error PSF_fit_X_error pixels 67 PSF fitted Y PSF_fit_Y pixels 68 PSF fitted Y error PSF_fit_y_error pixels 69 PSF fit chi-squared PSF_fit_chi2 - 70 nu PSF_fit_dof - 71 1D Sersic flux 1D_Sersic_flux ADU 72 Scale length 1D_Sersic_scale_len - 73 Power law index 1D_Sersic_index - 74 Error in 1D fit 1D_Sersic_fit_chi2 - 75 1D Sersic fit nu 1D_Sersic_fit_nu - 76 2D Sersic flux 2D_Sersic_flux ADU 77 Scale length 2D_Sersic_scale_len - 78 Power law index 2D_Sersic_index - 79 Error in 2D fit 2D_Sersic_fit_chi2 - 80 2D Sersic fit nu 2D_Sersic_fit_nu -
The attribute set and binary table format for CASU standard list-driven source re-measurement (known colloquially as `co-located list-driven photometry') shall be the same as the standard 80 parameter set described above, but some attributes will of course have subtle changes in their precise meanings as follows:
- RA and Dec shall be the input position, not a derived position;
- X and Y shall be the derived centre-of-gravity within a default aperture as opposed to the first moments of the thresholded, connected pixel distribution.
DETAILED DATA SPECIFICATION: VISTA
In general, the only difference between VISTA FITS and WFCAM FITS data shall be in the use of ESO hierarchical FITS headers. Of course, the exact keyword set used to describe VISTA data will be different to that for WFCAM. Appendix 9.4 gives example VISTA FITS headers, which illustrate use of ESO hierarchical FITS. This example is taken from AD03, where more details can be found.
Data obtained at the time of observation
Instrumental characteristics, set-ups and parameters shall be described by keywords as detailed in AD03; example FITS headers can be seen in Appendix 9.4.
Data products
Post-pipeline, and pre-archive, some extra header items will be added, notably the Quality-Control Measures; keyword sets shall be similar to the examples given in the Appendices for WFCAM data.
Corrected pixel data
In addition to those referenced above,
keyword categories as described in [1] shall be employed, e.g. Process (PRO) and Quality Control (QC) etc.
Additional example sets of hierarchical keywords are given in
Appendix 9.4.3.
Source catalogues
VISTA source extraction parameters shall be the same as those for WFCAM (see Section 5.2.2).
TRANSFER METHODS & PROCEDURES
Method
Transfer shall be via the Internet (i.e. JANET) or alternatively
a private internet (e.g. UKLight) using standard protocols
possibly tuned for optimal performance. The data to
be transferred shall reside in Cambridge on specific file systems;
WFAU has an account on this system.
Directories of processed nights data are set up as the pipeline is
running. While processing and writing to a given directory
is still running a directory lock file is used to
denote the `in progress' operations. After completion of
processing, the lock file is removed and
a semaphor file ('OK_TO_COPY') is
written enabling a remote client task to automatically
initiate data transfer to Edinburgh. Once the transfer is complete,
the WFAU transfer application writes a semaphor file
('SUCCESSFULLY_READ') into the nightly directory. WFAU shall
not copy any directory that has no OK_TO_COPY file present,
and of course will not recopy any directory with SUCCESSFULLY_READ
present. CASU shall not move or alter data in any way in the interval
between OK_TO_COPY being flagged and SUCCESSFULLY_READ
being written; after successful transfer, CASU are free to move/delete
data as and when necessary. In AD01 we give details of on-going
network bandwidth experiments with large data volumes and employing
various transfer protocols; transfer methods tested include ftp, scp,
GridFTP and sftp. Currently, a bespoke multithreaded scp application is
employed to transfer WFCAM data from CASU to WFAU, but it is
anticipated that a higher performance solution will be employed for VISTA data
(see AD01).
Procedure
Location of data is guaranteed by the pipeline and will be in an observation-date-driven directory structure to which WFAU will have secure, direct access. `Handshaking', e.g. notification of readiness, is achieved using a lockfile system as outlined above; verification of successful transfer includes automatic checking within the transfer utility employed via the number and size of files transferred.
In AD02, we give more details of the transfer task software, including error handling and transfer logging.
Updates
In the event of pipeline reruns over previous data (e.g. because of improvements in instrumental correction and/or source extraction software) the interface as a whole will be the same regardless of whether data being transfered is first-run or re-run as long as the archive system can cope with overwriting issues within and storage of repeat data. These are dealt with in the database design presented in AD02.
SECURITY ISSUES
Nightly processed data shall be held online at CASU until transfer of those data to WFAU is verified. As noted before, secure transfer protocols will be employed between CASU and WFAU to protect data from malicious corruption or access by unauthorised users. Although not strictly speaking a CASU/WFAU interface issue, raw data will be held online in Cambridge (and also offline in a tape store in another building) as the primary UK backup in case of any catastrophic data loss further down the data flow (raw WFCAM data is archived offline at JAC, and raw VISTA and WFCAM survey data at ESO/Garching).

BSCALE and BZERO shall default to 1.0 and 0.0 respectively if
absent from the keyword list. FLATCOR is used to tell the pipeline
how to do the flat fielding. If done, then it has the words 'Done with'
and the name of the flat field file.
RSTANOM is the reset anomaly correction. This example shows that
it has been done with a median-linear filter with box sizes of 50 and 25
pixels respectively. CIR_CPM is the confidence map.
PROV0000 simply gives the name of the current output image, while
PROVnnnn gives a list of the images that went to forming this image.
Note: RAZPmn and DECZPmn - the WCS is fit twice.
WCSPASS = 0 is just a WCS from header information.
WCSPASS = 1 is a fit to just the bright stars
and WCSPASS = 2 is a fit to all stars in the generated
catalogue. RAZPmn,DECZPmn is the zero-point shift between
WCSPASS = m and WCSPASS = n. For m = 0, n = 1 it's an indication
of how good the telescope pointing is. For m = 1, n = 2, it's
an indication of how good the fit is (e.g. do we even have the
right region here?) since for this combination the zeropoint
should be very small.
Note that the processed image data will be 32 bit integer. Although if one coaverages a set of dithered frames (not to mention flatfielding and so on) all the arithmetic is done using real numbers internally. When one creates the output product, to approximately maintain the original quantisation accuracy of the ADC one can `scale' the data on-the-fly using the normal CFITSIO routines by doing something along the following lines: if one sets up the output file with, say:
BITPIX = 32 / BZERO = 0.0 / BSCALE = 0.1 /
and then writes it out as call ftppre(outunit,1,1,npix,map,status)
where map is an r*4 array and reads it back via
call ftgpve(outunit,1,1,npix,nullval,sap,anynull,status)
one gets an rms error of 0.037; c.f. 0.37 with default BSCALE
of 1.0; if we use BSCALE = 1 / no-of-frames-in-stack
we stay at the ADC quantisation noise we started with, as if we had
coadded them.

correctly as one would expect. Furthermore, pixel data files expressed in this
way also compress more or less the same as normal int*4 files i.e. by
roughly a factor of 4 (although more extensive checks are needed to see
if this is really a typical factor and how the compression changes with
the number of images in a stack). Note that
