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.
A generic ANSI C version is also available from the author; it is
functionally similar to the Fortran version upon which the present
document concentrates.
