FOS Instrument Science Report 113 "Reference Guide and Complete History of FOS Calibration Reference Files and Tables" by Cynthia J. Taylor and Charles D. Keyes Abstract excerpted from the report: Complete tabulations of recommeded FOS reference files (except flat field, inverse sensitivity, and dead diodes) and reference tables AS OF 12 AUGUST 1994 are specified in convenient matrix format. Lists of recommended flat fields are covered in CAL/FOS-090 (C.D. Keyes and C.J. Taylor, April, 1993), inverse sensitivity is in CAL/FOS-093 (C.J. Taylor and C.D Keyes, June, 1993), and dead diodes is in CAL/FOS-112 (C.J. Taylor, August, 1994) and current lists of all three are found on STEIS in the /instrument_news/fos directory. ASCII and Postscript versions of the lists of recommended FOS reference files and table covered in this report are posted on STEIS in the /instrument_news/fos directory. A complete history of all reference files and tables delivered to Calibration Data Base System (CDBS) including superceded, redundant, and erroneous deliveries is also provided. Current recommendation lists and histories are to be maintained and made available to the FOS calibration team, analysis group, and the archive group. The history of all reference files and tables is not planned to be posted on STEIS. This report is aimed at internal users rather than the general observing community.
