It is CAL/FOS 146, "The FOS Dark Count-rate: Cycles 1 to 4" by Jeffrey J.E. Hayes and Don J. Lindler, April 1996 This document gives an analysis of all FOS dark observations taken on-orbit from Cycle 1 through Cycle 4. We find that overall, the FOS/RED dark count-rate is 0.0109 +/- 0.0022 counts/sec/diode, while for the FOS/BLUE, the count-rate is 0.0064 +/- 0.00083 counts/sec/diode. We confirm the finding of Rosenblatt et.al. (1992) of the correlation between dark count-rate and geo-magnetic latitude, but see no evidence for any correlation between geo-magnetic longitude, solar position angle, or solar cycle.

The programmers are responsible for design, coding, testing, and maintenance of the software used by the international astronomical community for the calibration and analysis of data from the Hubble Space Telescope. Programmers within the group work closely with astronomers on the ST ScI staff in developing software requirements and algorithms for instrument-specific tasks (including data analysis pipelines for new HST instruments). They also participate in larger development projects, often in collaboration with programming staff at other astronomical institutions, to enhance the system-level environment. Proficiency in C and Fortran and a working knowledge of the Unix and VMS operating systems are required. Experience with object-oriented languages such as C++ is desirable, as is experience with the IRAF data analysis system. A background in research data analysis and algorithm development for image or spectral data is required; an astronomical background is highly desirable. Excellent verbal and written communications skills are necessary. A Bachelor's Degree in Astronomy, Physics, Computer Science, or related field is required; an advanced degree is preferred. The successful candidate will have a minimum of two years experience in scientific software development. Substitution of additional relevant education or experience for stated qualifications may be considered. Females and minorities are encouraged to apply. These positions will remain open until suitable candidates have been found. Send a curriculum vitae, letter of application, and samples of C or Fortran code to: Human Resources Manager Space Telescope Science Institute 3700 San Martin Drive Baltimore, MD 21218 ================================================================================ RECENT PREPRINTS ---------------- We draw your attention to these papers, based on FOS data, that will appear in the next few months.
