DESCRIPTION:

The QA Frame Grade table contains the individual grade factors resulting from QA checks of the scan synchronization, frame image quality, frame noise, astrometric soundness, photometricity, and sensitivity (depth). These grade factors are combined to form a final score for each frame.

The QA Scan Grade Table contains the individual grade factors for a scan. These factors result from 
QA checks of scan synchronization and photometric quality. They combine to form a final score for 
each scan.


QA FRAME GRADE TABLE:

This table gives per-frame scores.

framescore = Frame Quality score.
      This is the minimum of the following grade factors multiplied by ten
qc = Quality of Completion. 
      Value is either 0.0 or 1.0.
qi = Quality of Image. 
      Values are 0.0, 0.1, 0.2, ... 1.0.
qn = Quality of Noise. 
      Values are 0.0, 0.1, 0.2, ... 1.0.
qa = Quality of Astrometry. 
      Values are 0.0, 0.1, 0.2, ... 1.0.
qd = Quality of Photometric Depth. 
      Values are 0.0, 0.1, 0.2, ... 1.0.

QA SCAN GRADE TABLE:

This metadata table gives per-scan scores.

scanscore = Scan Quality score.
      This is the minimum of the qs* and qp grade factors multiplied by ten.
qs1 = Quality of ScanSynch from 1x1 grid.
      Values are 0.0, 0.5, or 1.0.
qs5 = Quality of ScanSynch from 5x5 grid.
      Values are 0.0, 0.5, or 1.0. 
qp = Quality of Photometricity. 
      Values are 0.0, 0.1, 0.2, ... 1.0.
