... 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 . ...

If NFILTCAR (see section , ``Filter descriptors'') contains 1, a column headed FILTCODE_1 gives the code in raw data files that represents each position of the filter carrier. If multiple filter carriers are coded separately, the column FILTCODE_ n contains the coding for the n -th carrier. On the other hand, it may be convenient to combine two or more filter mechanisms into a single filter-code column in the instrument table. ...
