ABSTRACT
Persistence is the IR channel of WFC3 shows a power law decay with time. However, this behavior cannot extend to indefinitely to very short time
delays. Here we to attempt to measure departures from the power low time decay at short times, and to better characteize persistence in the IR
channel of WFC3. This should lead to a better model for persistence in the IR detector on WFC3 and thus to better estimates of how to remove
persistence within visits.
