FOS Instrument News # 117 "SMOV Report II. FOS Coarse Alignment 4907" by A.L. Kinney, A.P. Koratkar, O. Lupie, C.J. Taylor & C.D. Keyes Abstract excerpted from the report: Plate scale, orientation, and aperture positions can be derived from the FOS Coarse Alignment proposal 4907, run January 1, 1994. Since the initial updates must be done rapidly to allow the early run of the COSTAR/FOS alignment program, only aperture positions will be updated in the Science Instrument Aperture Files (SIAF) of the Project Data Base (PDB). Accurate updates will be made for all parameters following 4908, the FOS fine alignment program. For more information, please contact the above authors.
