katpoint 1.0a1

Karoo Array Telescope pointing coordinate library

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 Astropy to do the low-level calculations.

History

1.0a1 (2021-04-14)

• A mammoth rewrite to use Astropy 4.1+ and sgp4 instead of PyEphem (!11, !21)

• Depend on Python 3.6+ and remove all Python 2 fluff (!3, !12, !23)

• Use pytest and compare coordinates against Calc and Skyfield (!4, !7, !14)

• The new Body class encapsulates and vectorises coordinates (!6, !22)

• Timestamp/Antenna/Target mirrors Time/EarthLocation/SkyCoord (!5, !10, !22)

• Add tropospheric delays and proper NIAO to DelayCorrection (!13, !18, !20)
