0 Assigned ID: 2166 ----- Attempting Submission 1 (Thu May 23 23:12:31 GMT 2013) ----- Joint HST/XMM Changes from Previous Submission: * Initial Acquistion set to ACQ/SEARCH, COS/NUV Mirror A * Science Observations now have FP position changes only inbetween orbits. This increases the on target time by 390 sec, at the expense of on FP position receiving ~ 2x the exposure of the other 3. This long pointing could be placed in either orbits 2 or 3. * Question for COS Scientist: ETC gave the same buffer time, regardless of expousre time (see individual ETC runs listed in forms). I thought that this shouldn't be the case. -1419368695 ----- Attempting Submission 1 (Tue Jun 04 16:37:56 GMT 2013) ----- HST Phase II Proposal 13380 (1957_HST_APT_MultiFP_PhaseII.apt) successfully submitted. ----- Attempting Submission 2 (Thu Sep 19 15:40:05 GMT 2013) ----- We propose contemporaneous XMM-Newton and HST-COS observations of the black hole candidate 4U1957+11. We plan to search both the X-ray and UV spectra for evidence of a blue-shifted, magnetized wind, similar to that observed in high-resolution X-ray spectra of GRO J1655-40. The observation is to be a single visit, comprised of 3 HST-orbits, employing HST-COS with the G140L grating, centered on 1280 A, to observe the UV spectrum of the Low Mass X-ray binary 4U 1957+11 (also known as V1408 Aql). All four focal plane positions are to be employed. The HST-COS observation is to be coordinated with a contemporaneous XMM-RGS observation of the X-ray spectrum. A strictly simultaneous observation with XMM-RGS is not required; the HST-COS observation can be scheduled to start within +/- 24 hours of the start of the XMM-Newton observation. Target acquisition for HST-COS is to be obtained using near UV imaging. The current best estimated position for the source has been taken from Russell et al. (2011; ApJ, 739, L19), who used DSS images (USNO-B1, GSC 2.3, and 2MASS) to arrive at the source position. This position is within 0.2" of the mean position determined from two previous sets of Chandra-HETG observations (each with 90% confidence positional uncertainties of 0.6"). The source positional uncertainty thus falls within the range of 0.4"-0.7", and we therefore use a 2X2 near UV search mode followed by near UV imaging mode. Flux estimates are derived from the median value of Swift u-band measurements, converted to Johnson U-band, assuming a flat spectrum in F_\lambda. Variability about this median is expected to be +/-40%. These flux limits are too high for FUV imaging acquisition, but even under the most liberal assumptions are a factor of several below the near UV imaging flux limits. Scheduling should be coordinated with the XMM-Newton GOF.
