LMC X-3 High S:N Point Spread Functions in EPIC

CAL The bright LMC X3 binary will be observed with the EPIC cameras to tracethe PSF out into the wings. By use of different modes some correction forpileup may be achieved. The target ideally should be measured in its lowestflux state to minimise pileup effects. The Full window modes will capturethe wings of the PSF to high S:N with minimnal confusion from background and serendipitous sources, but significant pileup will occur in the PSF core. Asmall window mode in each case will be used measure the PSF core. (Assumed 2x2.7ksec overhead for EPIC in defining RGS and OM exposures). Tho observation maybe repeated at a lower flux state of the source, by rescheduling ca. 45 daysafter the first observation. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
