Authors:	Berry, D. S.
Abstract:	The AST library provides a comprehensive range of facilities for creating and using world coordinate systems that describe astronomical data. This paper gives a brief over-view of these facilities and a description of the integration of these facilities with the Starlink ``Extensible N-Dimensional Data Format'' (NDF), which stores bulk data in the form of N-dimensional arrays of numbers. Most of the major Starlink applications have been updated to take advantage of the facilities provided by this integration of AST and NDF.
