A FORTRAN callable library is provided for performing coordinate conversions, and specifications of the four routines expected to be of use to application programs are listed below. These in turn call four lower-level routines which are also supplied.

Note that all the routines required STATUS to be set to zero before they are called. A non-zero returned status signifies an error.

A tar file containing the source code of these routines can be obtained by ftp.

- SCOSPOS_ADTOXY - convert (RA,Dec) to (X,Y)
- SCOSPOS_R2SGF - convert radians to sexagesimal
- SCOSPOS_READHK - read transform coeffs etc. from the housekeeping file
- SCOSPOS_XYTOAD - convert (X,Y) to (RA,Dec)
