Karoo Array Telescope pointing coordinate library

Project description

katpoint

Coordinate library for the MeerKAT project, providing astronomical coordinate transformations, antenna pointing models, correlator delay models, source flux models and basic source catalogues, using an existing coordinate library such as PyEphem to do the low-level calculations.
