Definition of Quality Flags for GLIMPSE

Option: x0 (0=show all flags, x=hexadecimal)

0x01 (Sextractor) The object has neighbors, bright and close enough to significantly bias the photometry, or bad pixels (more than 10% of the integrated area affected).
0x02 (Sextractor) The object was originally blended with another one.
0x04 (Sextractor) At least one pixel of the object is saturated (or very close to).
0x08 (Sextractor) The object is truncated (too close to an image boundary).
0x10 (Sextractor) Object's aperture data are incomplete or corrupted.
0x20 (Sextractor) Object's isophotal data are incomplete or corrupted.
0x40 (Sextractor) A memory overflow occurred during deblending.
0x80 (Sextractor) A memory overflow occurred during extraction.
0x100  
0x200 (COMBO-17) potential problem from bright neighbours or reflexes from the optics (check images)
0x400 (COMBO-17) uncorrected hot pixels
0x800 (COMBO-17) erroneous photometry (set interactively)
