Abstract: AST is a general purpose library for manipulating coordinate systems stored within astronomical data in various forms (including FITS-WCS). It now includes support for reading and writing WCS information in the IVOA STC-S format, thus making all the power of AST available for manipulating STC-S regions and coordinate systems. These new facilities have been used within the CUPID clump finding package to allow clump catalogues created by CUPID to be more easily used within a VO context.
