Three main C code subroutine libraries used by OYSTER and included in the shared 64-bit library are the intellectual property of others. These are the Naval Observatory Vector Astrometry Subroutines (NOVAS), the Hierarchical Data System by STARLINK (HDS), and the Flexible Image Transport System I/O package by the High Energy Astrophysics Science Archive Research Center (FITSIO).

The OYSTER IDL code library also contains the The IDL Astronomy User's Library compiled by Wayne Landsman, and the OI-DATA IDL Utilities written by J. Monnier.

Starting with Version 8, OYSTER script code can be run under GDL 0.9.3. Please run command make -f Makefile.gdl to install.
