... HST . What filter should I use? ... A: Due to hardware limitations, the Clear (F583W) filter should not be used for any target brighter than visual magnitude m = 8.1. ... The Neutral Density (F5ND) must be used for targets brighter than m = 7.5. the Clear filter (F583W) cannot be used for targets brighter than m = 8.1. ... At the center of the field of view, a good "rule of thumb" is: targets fainter than m = 13 should be observed with the Clear (F583W) filter, brighter objects with PUPIL. ...

... 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 . ...
