FOS Instrument Science Report #108 "FOS Calibration Plan for SMOV" by A. Koratkar, C. Keyes, A. Kinney, I. Evans, and C. Taylor Abstract excerpted from the report: This instrument science report describes in detail the SMOV calibration program for the Faint Object Spectograph (FOS). A summary description of each program is given that includes proposal identification; estimated spacecraft time' primary targets (if any); detectors, apertures, and spectral elements used; and target acquisition techniques (if required). Also provided are the program abstract and scientific justification, a description of the observations, a summary of the primary program objective, and a listing of prerequisites and special requirements. Companion FOS Instrument Science Report CAL/FOS-109 provides similar information for the Cycle 4 FOS Calibration program. These two documents provide the complete description of all calibration programs deemed necessary to provide an inital working calibration of the FOS in the post-COSTAR era.
