		subarray_beam_id	ID of MCCS sub-array beam to configure. ID must be an integer between 1 and 48.
			type	integer
		station_ids	IDs of MCCS stations within this sub-array beamto configure. Array size must be less than 512, the maximum number of MCCS stations. Each item in the list must be an integer between 1 and 512.
			type	array
			items	type	integer
		update_rate	Update rate for pointing information. Value must be 0.0 or greater. TODO: clarify whether this is specified as a frequency or as a cadence, plus units.
			type	number
		channels	Channel block configurations. Each item in the list is a channel block configuration, each specified as a list of 4 numbers as follows: [start channel, number of channels, beam index, sub-station index] Constraints are: 0 < start channel < 376 start channel must be a multiple of 8 8 < number of channels < 48 1 < beam index < 48 1 < sub-station index < 8

		antenna_weights	Antenna weights. Maximum array size = 512 (=256 antennas x2 pols per sub-array beam). Antennas signals can be weighted to modify the station beam, varying from 0.0 for full exclusion to potentially 256.0 for an antenna contribution compensated for the number of antennas in the beam. This value is an amplitude multiplier added to that antenna signal before adding into the sum. Weights apply to all channels assigned to a beam.
			type	array
			items	type	number
		phase_centre	Phase centre offset for the station beam, in metres. The reference position for station phase must be modified to reflect antenna weighting and their contribution to the station beam. This offset can be can considered the desired centre of mass for the station. Constraints: array size = 2 -20 < phase centre value < 20
