... We describe a new library (AST) which provides a flexible high-level programming interface for handling world coordinate systems in astronomy and for producing graphical output. ... Relationships between coordinate systems are represented within AST by objects called Mappings. ... While Mappings represent the relationships between coordinate systems, the coordinate systems themselves are represented by objects called Frames. ... Like all objects, a Frame also provides methods. ...

... Representing Coordinate Systems (Frames) While Mappings represent the relationships between coordinate systems, the coordinate systems themselves are represented by objects called Frames. ... A Plot's base Frame corresponds with the native coordinates of the underlying graphics system. Plotting operations are specified, using AST Plot methods, in physical coordinates which correspond with the Plot's current Frame (typically this might be a celestial coordinate system). ...

... This has two reasons: (i) the logarithmic potential has no escape velocity so that it is more difficult to represent the VP on a finite velocity array; and (ii) the VP becomes discontinuous in the limit beta --> -infinity (only circular orbits), and singular in the limit beta --> 1 (only radial orbits) (e.g., van der Marel Franx 1993). ... The Gauss-Hermite moments obtained with both approaches agree well, and with the results in van der Marel Franx. ... Roeland van der Marel, marel@stsci.edu . ...
