Abstract:

The STAR 1program was prepared to replace a current SAMTEC Star Look Angle program run on the IBM 7094 computer by a program of higher accuracy which runs on the IBM 36065 computer. The program is organized in module form for easy use in other programs. The design accuracy neglecting refraction corrections is 0.01 arcseconds for both azimuth and elevation angles. This program, with the proper BLOCK DATA, will produce look angles at a given site for a given time block in hours for as many days as desired, up to January 1 of the next year. The coding was prepared in FORTRAN IV. Running speed is about 1.4 CPU seconds per star-station-day with polar motion corrections and a 12 hour integration step size. Author
