As we move closer to the time of the Servicing Mission (scheduled for Feb 1997), all remaining Cycle 5 and Cycle 6 programs are being scheduled so that they are completed before the Servicing Mission. The schedule insures that all WFPC2 and FOC imaging to be used as FOS and GHRS EARLY/ACQs will be performed before their corresponding spectroscopic science observations. FOS Personnel Changes ---------------------- The next few months will see substantial changes in the FOS team personnel. Stephan Martin left the FOS team on 1 May to take a position at Williams College. He has been replaced by Ed Smith, a long-time Data Analyst here at STScI. Anuradha Koratkar will be leaving the team effective 1 August to become the PRESTO Project Scientist here at STScI. Anuradha will continue to support the FOS programs for which she is the Contact Scientist. Michael Dahlem will be leaving the Institute on 1 August to take an ESA position with the X-ray Multiple Mirror Satellite (to be launched in 1999). Ron Downes will be picking-up Michael's Contact Scientist duties after Michael leaves. ================================================================================ NEW FOS DOCUMENTATION Two FOS Instrument Science Reports were distributed in May. To request paper copies of these reports, please send email to help@stsci.edu. CAL/FOS 147, "FOS Cycle 6 Calibration Plan", by M. Dahlem et al., May 1996 -------------------------------------------------------------------------- Abstract: This report describes the Cycle 6 (close-out) plan for the FOS as an active (as opposed to archival) instrument. No special calibrations will be performed. The plan calls for the use of 75 external target orbits and 128 orbits of internal orbit time. CAL/FOS 148 "Pre-COSTAR and Post-COSTAR Observed Point Spread Functions for the FOS" by A. Koratkar, May 1996. --------------------------------------------------------------------------- Abstract: In this report we provide the white light observed pre-COSTAR and post-COSTAR Point Spread Function (PSFs) and the Line Spread Functions (LSFs) for both the blue and red FOS detectors. The white light PSFs and LSFs have been determined from pre-COSTAR proposals 1528 and 3366, and post-COSTAR proposal 5626. These observed PSFs represent the FOS instrumental PSF convolved with the diode for each detector. A comparison of the pre-COSTAR LSFs with the model LSFs shows that the red detector LSFs are very similar and the blue detector model LSFs are underestimated. This is because of the strong dependence of the pre-COSTAR PSF on the optical telescope assembly focus changes. The comparison also shows that the color dependence of the LSFs is very small. Therefore, the white light LSFs can be used for any grating. A desciption of the format of the the electronic versions of the PSFs and LSFs is provided in the ADVISORY section of the FOS WWW page http://www.stsci.edu/ftp/instrument_news/FOS/topfos.html and the files themselves can be directly accessed at http://www.stsci.edu/ftp/instrument_news/fos/lsf_psf/ [Please note that "FOS" is upper-case in one URL and lower-case in the other.] ================================================================================ RECENT PREPRINTS ---------------- We draw your attention to these papers, based on FOS data, that will appear in the next few months.
