... The processing of these associated images presents new challenges to the HST data processing pipelines, which heretofore operated only on single images. ... Stage 1 (CALNICA) calibrates individual exposures without information from other members of the association. ... Stage 2 of calibration (CALNICB) only operates on associated images that have previously gone through CALNICA processing, and creates combined images for each distinct (non-overlapping) pointing within the association. ...

... The PPS pipeline is by design not intended to process EPIC or OM exposures performed using non-science modes or filters. ... A typical and rather frequent example of such exposures are the EPIC closed filter calibration exposures . At least one of such exposures in each EPIC camera is normally taken at the beginning of each XMM-Newton orbit. ... These closed filter EPIC calibration exposures represent therefore additional science OM and RGS exposure time. ... Pages maintained by SAS librarian . ...
