msmetadata.antennaoffset - Function

1.3.2 Get the offset position of the specified antenna relative to the array reference position.

Description

Get the offset position of the specified antenna relative to the array reference position. Antenna may be specified as a zero-based integer (row number in the ANTENNA table) or a string representing a valid antenna name. The returned record contains the longitude, latitude, and elevation offsets as quantity records. The reported longitude and latitude offsets are measured along the surface of a sphere whose center is coincident with the center of the earth and whose surface contains the observatory reference position.

Arguments


Inputs
which	Zero-based antenna in the ANTENNA table, or antenna name.
	allowed:	any
	Default:	variant 0

Returns
record

Example

    msmd.open("my.ms")
    # get the offset of the (zero-based) 3rd antenna in the ANTENNA table
    antennna_offset = msmd.antennaoffset(3)
    # get the offset of antenna DV02
    antennna_offset = msmd.antennaoffset(’DV02’)
    msmd.done()
