      Description

      Estimates of the noise in the bias frames coming from the USNO monocam run around ~20e- RMS. This is higher than with the same readout configuration in the lab, and could be due to several things.

      This ticket is to take a look at a few bias frames and investigate the structure of the noise. If it is periodic and at a constant phase then using master biases will significantly improve the SNR in the calexps produced, but if it is not, then whether or not bias frames should be used at all should be considered.
