2246  5  1  Note (5):    Three character flag, one character per band [JHK],
2246  5  2  thatvides a summary of the nhe net quality of the default photometry
2246  5  3  in each band, as derived from the Read Flag (Rflg), measurement
2246  5  4  uncenties ([jhk]cmsig), scanscan signal-to-noise ratios ([jhk]snr),
2246  5  5  framtection statistics (NdetNdet), and profile-fit reduced chi-squared
2246  5  6  values ([jhk]psfchi). The value for Qflg is set for a band
2246  5  7  accog to the precedence of tof the table below. For example, a source
2246  5  8  thattested and meets the con conditions for category "X" is not tested
2246  5  9  for subsequent qualities.
2246  5  10  
2246  5  11      X = There is a detection at this location, but no valid brightness
2246  5  12  estimate can be extracted using any algorithm. Rflg="9" and
2246  5  13  default magnitude is null.
2246  5  14  
2246  5  15  U = r limit on magnitude. So. Source is not detected in this band
2246  5  16  (Rflg="0"), or it is detected, but not resolved in a consistent
2246  5  17  fashion with other bands (Rflg="6"). A value of Qflg="U"
2246  5  18  does not necessarily mean that there is no flux detected in this
2246  5  19  band at the location. Whether or not flux has been detected can
2246  5  20  be determined from the value of Rflg. When Rflg="0", no flux
2246  5  21  has been detected. When Rflg="6", flux has been detected at the
2246  5  22  location where the images were not deblended consistently in all
2246  5  23  three bands (JHKs).
2246  5  24  
2246  5  25  F = This category includes Rflg="1" or Rflg="3" sources where a
2246  5  26  reliable estimate of the photometric error, [jhk]cmsig, could
2246  5  27  not be determined. The uncertainties reported for these sources
2246  5  28  in [jhk]cmsig and e_[jhk]mag are flags and have numeric
2246  5  29  values >8.0.
2246  5  30  
2246  5  31  E = This category includes detections where the goodness-of-fit
2246  5  32  quality of the profile-fit photometry was very poor (Rflg=2 and
2246  5  33  [jhk]psfchi>10.0), or detections where psf fit photometry did
2246  5  34  not converge and an aperture magnitude is reported (Rflg=4), or
2246  5  35  detections where the number of frames was too small in relation
2246  5  36  to the number of frames in which a detection was geometrically
2246  5  37  possible (Rflg="1" or Rflg="2").
2246  5  38  
2246  5  39  A = ctions in any brightnessness regime where valid measurements
2246  5  40  were made (Rflg="1","2" or "3") with
2246  5  41  [jhk]snr>10 AND [jhk]cmsig<0.10857.
2246  5  42  
2246  5  43  B = ctions in any brightnessness regime where valid measurements
2246  5  44  were made (Rflg="1","2" or "3") with

2246  5  51  D = ctions in any brightnessness regime where valid measurements
2246  5  52  were made (Rflg="1","2" or "3") with
2246  5  53  no [jhk]snr OR [jhk]cmsig requirement.
