For the master an expected master bias noise is calculated from the ron of the raw data, divided by the square root of the number of frames that were used to create the master bias. Then the population standard deviation of the pixel values of the master bias is determined, excluding all pixels that differ more than three times the expected ron from the median level of the master bias.
