SOME FORTRAN SUBPROGRAMS USED IN ASTRONOMY

Abstract

The note is a description of the subprograms DOP, which calculates the Doppler velocity of an earth-bound observer, JULDA which calculates the Julian day-number, MOVE which calculates precession, COORD which performs coordinate transformations, and the GRM series of subprograms which deal with Doppler velocities in terms of a standard galactic rotation model. These subprograms are written in basic FORTRAN and should be useable on a wide variety of computers.
