pint.observatory

Machinery to support PINT’s list of observatories.

This code maintains a registry of observatories known to PINT. Observatories are added to the registry when the objects are created. For the observatories defined in PINT, these objects are created when the relevant module is imported.

PINT’s built-in observatories are loaded when anyone imports the modules pint.observatory.topo_obs and pint.observatory.special_locations. This automatically happens when you call pint.observatory.Observatory.get(), pint.observatory.get_observatory(), or pint.observatory.Observatory.names() (pint.observatory.Observatory.names_and_aliases() to include aliases). Satellite observatories are somewhat different, as they cannot be created until the user supplies an orbit file. Once created, they will appear in the list of known observatories.

Normal use of pint.toa.get_TOAs() will ensure that all imports have been done, but if you are using a different subset of PINT these imports may be necessary.
