General description: This HTML file displays summary plots for the astrometry quality assurance. The astrometry is compared to several alternatives. The top row compares with a reapplication of the color terms (and to the right is shown the derived DR8 proper motions). The second row compares to the DR7 positions and proper motions. The following rows compare to the 2MASS, USNO-B, UCAC-3 plus r14, and UCAC-3 catalogs.
Badly calibrated or otherwise marked fields have been removed,
using the condition that the field score is greater than
0.5.
Naming convention: astromqa-NRA-NDEC.html (NRA and NDEC define the resolution of the image used to make the plots)
