qaz MTF Extraction Stage Q/A Statistics
qaz files are the Quality Assurance parameter files for the GEOMPIPE subsystem of the VMICAL reduction stage.
The QA files generated for GEOMPIPE include a list of FILLED images, a file containing the Point Spread Function QA parameters generated by GEOM and culled from the image headers, a file containing the HGEOM QA parameters culled from the image headers, and a file containing the updated image geometry ellipse parameters generated by GEOM and culled from the image headers.
These QA parameters include the following:
CHI2 reduced chi-squared of the least-squares fit performed by HGEOM SLR scattered light ratio LMB_GRAD gradient at the radius that HGEOM determines to be the "limb" C_MA corrected major axis C_MI corrected minor axis EXT_SLOP slope of the sky extension A(1) coefficient of the PSF A(1)_ERR errors of the coefficient A(2) A(2)_ERR A(3) A(3)_ERR FNDLMBXC X center coordinate FNDLMBYC Y center coordinate FNDLMBMI updated minor axis FNDLMBMA updated major axis FNDLMBAN ellipse angle
These QA files are bundled into the VMICAL QA files, qac, for data from 960801 and after.
