cc_flags allwise_sc2 WISE Contamination and confusion flag. Four character string, one character per band [W1/W2/W3/W4], that indicates that the photometry and/or position measurements of a source may be contaminated or biased due to proximity to an image artifact. CAUTION: Non-zero cc_flags values in any band indicate the the measurement in that band may be contaminated and the photometry should be used with caution. varchar 4      
The type of artifact that may contaminate the measurements is denoted by the following codes. Lower-case letters correspond to instances in which the source detection in a band is believed to be real but the measurement may be contaminated by the artifact. Upper-case letters are instances in which the source detection in a band may be a spurious detection of an artifact.
  • D,d - Diffraction spike. Source may be a spurious detection of (D) or contaminated by (d) a diffraction spike from a nearby bright star on the same image, or
  • P,p - Persistence. Source may be a spurious detection of (P) or contaminated by (p) a short-term latent image left by a bright source, or
  • H,h - Halo. Source may be a spurious detection of (H) or contaminated by (h) the scattered light halo surrounding a nearby bright source, or
  • O,o (letter "o") - Optical ghost. Source may be a spurious detection of (O) or contaminated by (o) an optical ghost image caused by a nearby bright source, or
  • 0 (number zero) - Source is unaffected by known artifacts.
A source extraction may be affected by more than one type of artifact or condition. In this event, the cc_flags value in each band is set in the following priority order: D,P,H,O,d,p,h,o,0. The full tally of artifacts affecting a source in each band is given in the w?cc_map and w?cc_map_str columns. A source can appear in the AllWISE Source Catalog even if it is flagged as a spurious artifact detection in a band if there is a reliable detection in another band that is not flagged as a spurious artifact detection. Entries in the AllWISE Reject Table may be flagged as spurious detections of artifacts in all bands.

chi2 calVariability WSACalib Chi-squared value of astrometric solution real 4   -0.9999995e9 FIT_CHI2
The Variability table contains statistics from the set of observations of each source. At present, the mean ra and dec and the error in two tangential directions are calculated. The "ra" direction is defined as tangential to both the radial direction and the cartesian z-axis and the "dec" direction is defined as both the radial direction and the "ra" direction. Since the current model is just the mean and standard deviation of the data, then the chi-squared of the fit=1. Data from good frames across all bands go into the astrometric model determination. This will include bands in non-synoptic filters: the one observation in these bands can help. In future releases a fit will be made to the rms data as a function of magnitude in each band, as has already happened for photometric data and a motion model that incorporates proper motion (and possibly parallax) will be used. The motion model is a parameter in the VarFrameSetInfo table.

smallint 2     CLASS_MISC
A discrete classification code for each detected image, based on various cuts on morphological parameters (see the Glossary entries for classStat and ell for further details). It is primarily based on cuts on the stellar profile statistic classStat and necessarily trades-off completeness against reliability between point-like (e.g. stellar) and extended (e.g. galaxy) images. The class assignments are as follows:
FlagMeaningGenerally satisfies
-2Probable star+2.0≤classStat≤+3.0
-1Star-3.0≤classStat≤+2.0
0NoiseclassStat≤-3.0
+1GalaxyclassStat≥+3.0

but these are also moderated by ellipticity overrides (e.g. ellipticity≥0.9 is flagged as class 0) and magnitude-dependent information (e.g. near or at saturation objects are preferentially flagged as class -1). Hence class is conservative in the sense that it defines galaxy samples optimised for completeness, and conversely point-source samples optimised for reliability. For examples of the use of the various classification attributes in sample selection, especially with respect to the trade-off between completeness and reliability for point/extended samples, see the Views predefined in the WSA schema (these can be examined using the schema browser). For much more information concerning the class attribute, see the CASU standard source extraction documentation.

classStat calDetection WSACalib N(0,1) stellarness-of-profile statistic {catalogue TType keyword: Statistic} real 4     STAT_PROP
An equivalent N(0,1) measure of how point-like an image is, used in deriving the class attribute in a 'necessary but not sufficient' sense. Derived mainly from the curve-of-growth of flux using the well-defined stellar locus as a function of magnitude as a benchmark (see Irwin et al. 2004 SPIE 5493 411 for more details). Note that the assignment of the discrete classification flag class=-1 is based on a cut of -3.0≤classStat≤+2.0 cut on this statistic (along with ellipticity and magnitude information) and hence is conservative in the sense that it defines galaxy samples optimised for completeness, and conversely stellar samples optimised for reliability.

Derived mainly from the curve-of-growth of flux using the well-defined stellar locus as a function of magnitude as a benchmark (see Irwin et al. 2004 SPIE 5493 411 for more details). Note that the assignment of the discrete classification flag class=-1 is based on a cut of -3.0≤classStat≤+2.0 cut on this statistic (along with ellipticity and magnitude information) and hence is conservative in the sense that it defines galaxy samples optimised for completeness, and conversely stellar samples optimised for reliability. For examples of the use of the various classification attributes in sample selection, especially with respect to the trade-off between completeness and reliability for point or extended samples, see the Views predefined in the WSA schema (these can be examined using the schema browser).

classStat udsDetection WSA S-Extractor classification statistic CLASS_STAR (0 - galaxy, 1 - star) {catalogue TType keyword: Statistic} real 4     STAT_PROP
CLASS_STAR is SE's classification of objects on the basis of a Neural Network Output. There are several input parameters which are directly linked to the CLASS_STAR parameter:
PIXEL_SCALEPixel size in arsec.
SEEING_FWHMFWHM of stellar images in arcsec.
BACK_SIZESize, or Width, Height (in pixels) of a background mesh.
THRESH_TYPEMeaning of the DETECT_THRESH and ANALYSIS_THRESH parameters: RELATIVE (scaling factor to the background rms) or ABSOLUTE (absolute level)
ANALYSIS_THRESHThreshold (in surface brightness) at which CLASS_STAR and FWHM operate: 1argument (relative to background rms) or 2 arguments (mu[mag/arcsec²], zero-point [mag])

A perfectly point-like (stellar) object has class=1.0.

cntr allwise_sc2 WISE Unique identification number for this object in the AllWISE Catalog/Reject Table. This number is formed from the source_id, which is in turn formed from the coadd_id and source number, src. bigint 8      
The cntr value is formed by making the source_id into an integer, in the format: RRRRsDDDtrevIIIIII, where
  • RRRR = Tile center RA in deci-degrees, truncated not rounded (e.g. RRRR=int[10*ra]), as in the coadd_id.
  • s = Tile center Declination sign translated from "p" or "m" into "1" or "0", respectively.
  • DDD = Tile center Declination in deci-degrees, as in the coadd_id. For positive declinations, the tenths of a degree is truncated not rounded (e.g. DDD=int[10*dec]). For negative declinations, the tenths of a degree is always truncated leftward on the number line (e.g. DDD=ceil[10*abs(dec)].
  • [trev] = Disambiguation string, translated where necessary into digits corresponding to the letters' places in the alphabet.
    • t - Tile type translated into two digits, zero-filled ("a" = "01").
    • r - Data Release identifier translated into a single digit, (For AllWISE: "c" = "3").
    • e - Survey Phase ("5" = AllWISE [Full cryogenic + 3-Band Cryo + Post-Cryo]).
    • v - Processing version.

    The translated disambiguation string is always 01351 for AllWISE.

  • IIIIII = six-digit, zero-filled, sequential extracted source number, src, within the Tile.

For example, a source in the Tile 3041m137_ac51, with a source_id of '3041m137_ac51-012345', has a cntr value of 3041013701351012345.

NOTE: AllWISE Catalog and Reject Table entries are cross-referenced with the Multiepoch Photometry (MEP) Database via the cntr identifier. The Catalog/Reject Table cntr value is referred to as cntr_mf in the MEP Database.

coadd twomass_xsc 2MASS 3-digit coadd number (unique within scan). smallint 2     NUMBER
coadd_id allwise_sc2 WISE Atlas Tile identifier from which source was extracted. varchar 20      
The identifier has the general form: RRRRsDDD_[trev], where
  • RRRR = Tile center RA in deci-degrees, truncated not rounded (e.g. RRRR=int[10*ra]).
  • s = Tile center Declination sign ("p"="+", "m"="-")
  • DDD = Tile center Declination in deci-degrees. For positive declinations, the tenths of a degree is truncated not rounded (e.g. DDD=int[10*dec]). For negative declinations, the tenths of a degree is always truncated leftward on the number line (e.g. DDD=ceil[10*abs(dec)].
  • [trev] = Disambiguation string.
    • t - Tile type ("a" = Atlas)
    • r - Data Release ("c" = AllWISE)
    • e - Survey Phase ("5" = AllWISE [Full Cryogenic + 3-Band Cryo + Post-Cryo])
    • v - Processing version.

    The disambiguation string is always ac51 for Tiles in the AllWISE Release products.

CONFUSED twoxmmi_dr3_v1_0 XMM This flag (True/False) signifies that the 3-sigma error circle of a detection within this unique source overlaps the 3-sigma error circle of a nearby unique source. As such, it is an indicator of possible confusion (uncertainty) about the assignment of detections between sources. varchar 5      
CONFUSED xmm3dr4 XMM Normally set 0 (= False), but set 1 (= True) when a given detection has a probability above zero of being associated with two or more distinct sources. The SRCID is that of the match with the highest probability, but there remains some uncertainty about which source is the correct match for the detection. bit 1
