 | | The run's QA page gives statistics of a wide variety of internal consistency statistics run on the data, with links to specific postscript figures (and in some cases, tables of numbers) giving the gory details. |
 | | Finally, the rms statistic in bins does not measure the number of extreme outliers from the stellar locus, so also shown is the number of stars more than 2 sigma from the median s, w, x, and y values, on the blue side and red side, respectively. |
 | | As this example shows, this is a very powerful statistic, and checks for consistency of the internal photometric calibration and the flat-fields at the level of much better than a percent. |
