      Description

      The astrometry histogram generated by validateDrp.py conflates astrometric and photometric calibration because it uses magnitude for brightness, and this relies on the accuracy of the photometric calibration. Colin Slater suggests (and I agree) that brightness should be based on signal to noise ratio, thus making the astrometry histogram independent of photometric calibration.
