Description:

SLALIB is a library of routines intended to make accurate and reliable
positional-astronomy applications easier to write. Most SLALIB
routines are concerned with astronomical position and time, but a
number have wider trigonometrical, numerical or general applications.
The applications ASTROM, COCO, RV and TPOINT all make extensive use of
the SLALIB routines, as do a number of telescope control systems
around the world. The SLALIB versions currently in service are written
in Fortran 77 and run on VAX/VMS, several Unix platforms and PC.
