| | 3 | I forgot to plot and post the results obtained from the final changes to psStats. The following plot shows the difference in the background levels for the entire SAS set. The "new" statistic is calculated using the updated psStats code, and the "old" statistic is the one originally obtained with the current working tag (ipp-20130712). The new statistics have mean/median/min/max values that are shifted by about 0.25 count relative to the old statistic, indicating that the new statistic believes the sky to be slightly brighter than was obtained previously. The distribution of sigma values is centered around zero, as there should not be a systematic shift between statistic calculations. |
