The GHRS and FOS are being withdrawn from HST at the time of the Second Servicing Mission, now scheduled for February 13, 1997. Every effort is being made to complete GHRS and FOS observations before that date, but please remember that the lead time for scheduling observations, combined with the time needed to process HOPRs (HST Operations Problem Reports) means that HOPRs need to be filed by mid-December if there is any hope of carrying out a repeat observation before SM2. If there are problems with your observations, you can file a HOPR via the WWW at the URL: http://www.stsci.edu/public/hopr_instruct.html Flat Fields ----------- We have recently become aware of two new features on the flat for the FOS/RD G400H grating. The first feature is centered at pixel ~390 and extends from pixels 387 to 407. It is rather flat but is not a dead diode. The second feature is centred at pixel 420 and ranges from pixels 412 to 430, and is rather like a broad absorption line. Both features appear to have arisen in late 1995 and have developed into roughly 6-7% effects since January 1996. The FOS team is in the process of delivering a new set of flats for all gratings, including a new G400H/RED correcting for these features, within the next month. A formal announcement to the community on their availability will be made through the STAN and on the FOS Web page. ================================================================================ Data Analyst Position Available at STScI ---------------------------------------- The Space Telescope Science Institute anticipates an opening for a Data Analyst. Data Analysts in the Science Support Division help General Observers and Archive Researchers analyze HST data, work with Instrument Scientists in calibrating the HST instruments, and work with STScI staff on grant-supported research projects. These research projects span a range of size scales from comets and planets to the large scale structure of the universe and a range of wavelengths from radio to X-ray astronomy. Applicants should possess a B.S. degree in astronomy or physics, or equivalent; experience with astronomical research; familiarity with scientific computing; expertise in data analysis; knowledge of IRAF, IDL or other software packages for astronomical data analysis; and programming ability. Additional mathematical, statistical, and computer skills are desirable. Candidates should have the ability to work with a minimum of direction, enjoy research and possess skills to develop excellent working relationships. Candidates should send a letter with current curriculum vitae and the names of three references to: Human Resources Manager Space Telescope Science Institute 3700 San Martin Dr. Baltimore, MD 21218 Women and minorities are strongly urged to apply. AAE/EOE. ================================================================================ RECENT PREPRINTS ---------------- We draw your attention to these papers, based on FOS data, that will appear in the next few months. This list includes all preprints received by the STScI Library not yet published in the journals. Please remember to include our Library in your preprint distribution list.
