SLALIB

SLALIB -- the name just stands for Subprogram Library, -- a collection of subprograms designed for use in certain types of astronomical application software. Although previous versions were in ForTran only, the current version contains both C and Fortran libraries.

Most of the routines are concerned with astronomical position and time, but a number have wider trigonometrical, numerical or general applications, and one or two are essentially miscellaneous.
