NRCO 63: Pinhole search in MOS1 medium filter

Since an MOS1 instrument anomaly (possible meteorite impact) in rev. 961, MOS1 CCD6 is inactive. We propose to check whether a pinhole can be identifiedin the MOS1 medium filter (e.g. due to micrometeorites), inside the filter areawhich, in nominal position, is located above the now inactive CCD6 (ref.as F6area). Therefore this F6 area must be moved above active CCDs by moving thefilter wheel out of the nominal position. The filter wheel position must bechanged two times, first by 12 degrees, second by 8 degrees, into the directionof the thin2 filter, to place the largest possible fraction of the F6 areaabove active CCDs. For each position a set of 5 FF RPP mode diagnostic exposuresmust be be taken from three CCDs (1,2,7). truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
