class Detection SSA Classification flag tinyint 1 CLASS_OBJECT

class dxsDetection, dxsListRemeasurement, gcsDetection, gcsListRemeasurement, gpsDetection, gpsListRemeasurement, lasDetection, lasListRemeasurement, udsListRemeasurement WSA Flag indicating most probable morphological classification {catalogue TType keyword: Classification}
-1 stellar, +1 non--stellar, 0 noise, -2 borderline stellar, -3 boderline galaxy, -9 saturated 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:

Flag Meaning Generally satisfies

-2 Probable star +2.0≤classStat≤+3.0

-1 Star -3.0≤classStat≤+2.0

0 Noise classStat≤-3.0

+1 Galaxy classStat≥+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 preferentailly 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.

Using the SE classification statistic (see the corresponding entry for classStat), a CASU-like discrete classification code is assigned for each detected object as follows:

Flag Meaning

-9 Saturated

-3 Probable galaxy

-2 Probable star

+1 Galaxy

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. 1994 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_SCALE Pixel size in arsec.

SEEING_FWHM FWHM of stellar images in arcsec.

BACK_SIZE Size, or Width, Height (in pixels) of a background mesh.

THRESH_TYPE Meaning of the DETECT_THRESH and ANALYSIS_THRESH parameters: RELATIVE (scaling factor to the background rms) or ABSOLUTE (absolute level)

ANALYSIS_THRESH Threshold (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.
