Scientific paper

We report the presence of image persistence in NICMOS data due to prior saturation ofthe array by the bright Earth as well as an algorithm to remove its impact. BEP (BrightEarth Persistence) may occur when ACS and NICMOS are used in parallel, and the datadump of ACS delays the insertion of the NICMOS filter blank as long as 6 minutesbeyond the Bright Earth avoidance angle. We have constructed a BEP frame which canbe used to model and remove the presence of BEP in NICMOS data. The algorithm isseen to remove 99.5% of the variance in the background of BEP impacted Camera 2data. Ongoing work involves broadening the applicability of the BEP correction to Camera 1 and 3 and making it available as a pyraf script through STSDAS.
