WGACAT (1995)vs WGACAT (2000) Quality Flags

<
< The quality flags used in 1995 and 2000 versions of WGACAT are compared. < There are 13 (0-12) quality flags in WGACAT as release in May 2000 as < opposed to 11 (0-10) quality flags in the 1995 version.

Quality FlagsWGACAT (1995)WGACAT (2000)
12-A secure detection of a point source
11-Good detection located near the inner detector support structure(at ~20 arcmin radius)
10A secure detection of a point sourceGood detection located near the outer edge of detector or near the support structure < of the detector ("ribs") at offaxis > 20 arcmin radius.
9- Good detection. < This quality flag is used to indicate that the thumbnails have not an < optimized rebinning for the source strength and the source appeared < split with a separation of about 10 arcsec, well inside the 80% HPD < of the PSF. These sources are mostly at large offaxis and low rate < (< 1e-2 count/s).
8The source detections in the entire field < are secure as a whole. But the individual sources are not inspected.Good detection.This quality flag is used to indicate that the thumbnails have not an < optimized rebinning for the source strength and the source appeared < split with a separation less 5 arcsec, well inside the 80% HPD < of the PSF. These sources are mostly at small offaxis and low rate < (< 1e-2 count/s).
7-Good detection, but is located within bright background due to extended emission such < as clusters, supernova remnants or near bright X-ray binaries.
6-The point source detection is good but it is weak source.
5The source detection is suspicious due to < the existence of bright emission features such as clusters, SNRs etc. in the < field of viewThe source detection is good, but it may be extended or elongated.
4Many (typically more than a half) of the detections are caused by extended < emission,but there are still good sources The detections are spurious due to nearby bright sources and also located at < (or near) the inner ring, the edge or the ribs of the detector
3The source looks perfectly good but is really bad. < This may result from a local arc in the detector caused by a temporary HV breakdown < or by a mystery pointing that interrupt the sequenceAlthough the source looks good, it is not a real detection. < This may result from a local arc in the detector caused by a temporary HV breakdown < or by mystery pointings that interrupts the sequence. This flag also used as < the indicator for Supernova remnants that are extended over the field.
2The observation was taken within the first 2 months of the mission (June - July 1990) < where the processing and satellite were unstableThe observation was taken within the first 2 months of the mission (June-July 1990) < where the processing and satellite were unstable. One of all double-counted sources < detected in between "in", "in2" and "out" regions and duplicate sequences is suppressed < by assigning QFlag=2.
1Most of the detections in the field are spurious because of a large extended object The source detection is false caused by spurious detections due to extended < emission from bright Supernova remnant or Low Mass X-ray Binary in the field
0-Same as QFLAG 1, but the spurious < detections are caused by clusters
