class pyuvdata.telescopes.Telescope[source]

A class for defining a telescope for use with UVData objects.

citation

text giving source of telescope information

Type:: str

telescope_name

name of the telescope

Type:: UVParameter of str

telescope_location

telescope location xyz coordinates in ITRF (earth-centered frame).

Type:: UVParameter of array_like

antenna_diameters

Optional, antenna diameters in meters. Used by CASA to construct a default beam if no beam is supplied.

Type:: UVParameter of float

pyuvdata.telescopes.known_telescopes()[source]

Get list of known telescopes.

Returns:: list of str – List of known telescope names.

pyuvdata.telescopes.get_telescope(telescope_name, telescope_dict_in=None)[source]

Get Telescope object for a telescope in telescope_dict.

Parameters:

telescope_name (str) – Name of a telescope
telescope_dict_in (dict) – telescope info dict. Default is None, meaning use KNOWN_TELESCOPES (other values are only used for testing)

Returns:

Telescope object – The Telescope object associated with telescope_name.
