Mappings Available  

The basic concept of a Mapping ([*]) is rather generic and obviously it is necessary to have specific Mappings that implement specific relationships between coordinate systems. AST provides a range of these, to perform transformations such as the following and, where appropriate, their inverses:

Further reading: For a more complete description of each of the Mappings mentioned above, see its entry in [*]. In addition, see the discussion of the PermMap in [*], the UnitMap in [*] and the IntraMap in [*]. The ZoomMap is used as an example throughout [*].
