Issue DM-5252: Base "bright star" cut on S/N instead of magnitudes
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. [~ctslater] suggests (and I agree) that brightness should be based on signal to noise ratio, thus making the astrometry histogram independent of photometric calibration.
