properties
config_id	type	string
subarray_id	Subarray number
	type	integer
eb_id	Execution block ID to associate scan configs to an observation. This ID is used for associating generated data, especially data products, for a given observation. Multiple scans can be linked to one observation and this ID is used as metadata to associate the data products from all scans of the same observation. This ID does not have to be unique for a scan configuration but should be unique for different observations. For example, all the data and weights files will have an EB_ID header value populated with the value supplied in this field.

Input for Band 5a and 5b consists of two 2.5 GHz streams; the center frequency can be independently tuned for each stream. The following nomenclature is used to refer to Band 5a and 5b streams: 5a1, 5a2, 5b1, 5b2.

type	object
properties
frequency_band_offset_stream1	Optionally, an offset can be specified so that the entire observed band is shifted (to accommodate a Zoom Window that crosses a ‘natural’ Frequency Slice boundary). If specified, applies for all the receptors in the sub-array. Bands 1 and 2: input from the receptor consists of a single data stream; the Frequency Band Offset (FBO) should be specified for Stream 1 only. Bands 5a and 5b: input from the receptor consists of two data streams; the FBO can be specified for each stream independently. Note: For Band 5a and 5b the frequency shift is performed by the receptor (DISH). Note: This is optional and does not need to be implemented in PI3, but would be great for demo; if Team Buttons is looking for opportunities to showcase interesting GUIs, Zoom Windows are perfect opportunity (would require TMC and CSP to support these two parameters, corrBandwidth values > 0 and zoom window tuning.)
	type	integer
frequency_band_offset_stream2	See frequencyBandOffsetStream1
	type	integer
delay_model_subscription_point	FQDN of TMC.DelayModel TANGO attribute which exposes delay values for all the dishes assigned to a Subarray in JSON format. Delay values are updated every 10 seconds.
	type	string
doppler_phase_corr_subscription_point	The same model applies for all receptors that belong to the subarray. Delivered by TMC using publish-subscribe mechanism (see ICD Section 3.8.8.5.3). The Doppler phase correction, by default, applies only to the CSP_Mid Processing Mode Correlation; optionally may apply to other Processing Modes as well.

function_mode	allOf	type	string
		enum	CORR, PSS-BF, PST-BF, VLBI
receptors	Optionally a subset of receptors to be correlated can be specified. If not specified, all receptors that belong to the subarray are cross-correlated (i.e. visibilities for all the baselines in the subarray are generated and transmitted to SDP). Valid receptor IDs include: SKA dishes: “SKAnnn”, where nnn is a zero padded integer in the range of 001 to 133. MeerKAT dishes: “MKTnnn”, where nnn is a zero padded integer in the range of 000 to 063.

frequency_slice_id	Frequency Slice to be processed on this FSP (valid range depends on the Frequency Band).
	type	integer
zoom_factor	Bandwidth to be correlated calculated as FSBW/2n, where n is in range [0..6]. When n=0 the full Frequency Slice bandwidth is correlated. BW > 0 implies ‘Zoom Window’ configuration; the spectral Zoom Window tuning must be specified.
	type	integer
zoom_window_tuning	The Zoom Window tuning provided in absolute terms as RF center frequency. Based on that, CSP_Mid calculates tuning within the data stream received from the receptor. Must be selected so that the entire Zoom Window is within the Frequency Slice. If partially out of the FS a warning is generated. If completely outside of the FS an exception is generated. Step size <= 0.01MHz. The Frequency Band Offset can be used to shift the entire observed band in order to accommodate a Zoom Window that spans across a Frequency Slice boundary.
	type	integer
integration_factor	Integration time for the correlation products, defines multiple of 140 milliseconds.
	type	integer
output_mac	Output MAC address to send visibilities to for every channel, given as a list of start channel ID to IEEE 802 MAC addresses. Where no value is given for a concrete channel, the previous value should be used.

				type	string
channel_averaging_map	Table of up to 20 x 2 integers. Each of entries contains: Start channel ID, and averaging factor. Explanation: Each FSP produces 14880 (TBC) fine channels across the correlated bandwidth (Frequency Slice or Zoom Window). Channels are evenly spaced in frequency. TM shall provide the table that for each FSP and each group of 744 channels (there are 20 groups per FSP) indicates the channel averaging factor. More precisely, for each group the TMC provided table specifies: the channel ID (integer) of the first channel, and the averaging factor, as follows: 0 means do not send channels to SDP, 1 means no averaging, 2 means average two adjacent channels, 3 means average three adjacent channels, and so on. If no entry is present for an FSP, the averaging settings of the previous FSP are still applicable.
	type	array

		items	type	integer
channel_offset	Channel ID to use for visibilities of the first channel produced by this FSP. For example, if the channel offset is 5000 the first channel group would span IDs 5000-5743. Note that this offset does not apply to channel maps in this structure (such as channelAveragingMap or outputHost).
	type	integer
output_link_map	Output links to emit visibilities on for every channel, given as a list of start channel ID to link ID. Where no value is given for concrete channel, the previous value should be used.
	type	array
	items	type	array
		items	anyOf	type	integer
				type	string
