WFC3 Persistence after worst actors
Abstract
The goal of this calibration program is simply to measure the persistence associated with all of the sources we have declared to be Worst Actors. This will allow us to determine whether the special observations in the Worst Actor category are well described by our persistence model. Furthermore, many Worst Actors are taken in a subarray mode. Hence, the only way to determine how much persistence there is outside the subarray is with full frame observations. Obtaining darks after these Worst Actors allows us to estimate the amount of persistence outside of the subarray, where the strong persistence caused by the "dwell time" peaks.
