Astronomy: Time and Position Functions, Misc. Utilities

Description

Collection of time, position, and utility functions for astronomy: Julian and Modified Julian Day transformations, J2000/B1950 coordinate transformations, GMST at 0h from UT, UT to LST and hour angle, angular unit transformations and distance, etc. Precision generally at the level of a millisecond in time for JD, 0.1 s for LST, and a few tenths of an arcsecond in position for B2000-J1950 and vice versa. Additional functions include flux from thermal disk-shaped source, and others. Functions were originally assembled to support single-dish radio astronomy planning and observations. Cosmology-related functions are in the cosmoFns package.
