If pointing.wrap_sector is not in the JSON, TMC will make no sector change.

			projection	5.0*
				type	object
				default	SIN
				properties
				name	Projection type. Must be one of ‘SIN’, ‘TAN’, ‘ARC’, ‘STG’, ‘CAR’, or ‘SSN’, though values are not case sensitive. Defaults to ‘SIN’. The following projections are implemented: Orthographic (SIN): This is the standard projection in aperture synthesis radio astronomy, as it ties in closely with the 2-D Fourier imaging equation and the resultant (l, m) coordinate system. It is the simple orthographic projection of AIPS. Gnomonic (TAN): This is commonly used in optical astronomy. Great circles are projected as straight lines, so that the shortest distance between two points on the sphere is represented as a straight line interval (non-uniformly divided though). Zenithal equidistant (ARC): This is commonly used for single-dish maps, and is obtained if relative (cross-el, el) coordinates are directly plotted (cross-elevation is azimuth scaled by the cosine of elevation).It preserves angular distances from the reference point. Stereographic (STG): This is useful to represent polar regions and large fields. It preserves angles and circles. Plate carree (CAR): This is a very simple cylindrical projection that directly maps azimuth and elevation to a rectangular (x, y) grid, and returns offsets from the reference point on this plane. The x offset is therefore equal to the azimuth offset, while the y offset is equal to the elevation offset. It does not preserve angles, distances or circles. Swapped orthographic (SSN): This is the standard SIN projection with the roles of reference and target points reversed. It is useful for holography and other beam pattern measurements where a dish moves relative to a fixed beacon but the beam pattern is referenced to the boresight of the moving dish.

PST_Rescale_configuration_3.0

PST specific parameters used for rescaling of data before requantisation. This is used within the FLOW_THROUGH processing mode.

type	object
properties
algorithm	The algorithm used to determine the scales and offsets when rescaling complex voltage data in Flow Through mode. The value MedianMAD is the default algorithm and PST will determine the scales and offsets based on the calculating the median and the median absolute deviation (MAD) as the proxies for the sample mean and standard deviation. These statistics are considered more robust against outliers and are less affected by radio frequency interference (RFI) when computing the values. The value MeanStdDev will calculate the sample mean and standard deviation of the input data and use that to rescale the data. This algorithm is not robust against RFI which will reduce the dynamic range when performing requantisation of the data. Default: MedianMAD
	default	MedianMAD
	allOf	type	string
		enum	MedianMAD, MeanStdDev
periodic_update	An indicator for whether to recalculate the rescale statistics periodically. The rescaling of data within the FLOW_THROUGH processing mode can either be calculated once and applied across all the data during the scan or can be calculated periodically. If this value is set to false then the former is performed while the latter is performed if the field is set to true. Default: false
	type	boolean
	default	False
timescale	The timescale needed to calculate rescale stats, in seconds. This value is how long in time to sample data before calculating the rescale statistics. If periodic_update is true, then this is also the period of how often the rescale stats are recalculated. If this value is set to 0.0, then PST will use the smallest chunk of data available to it to perform the statistics calculation. Default: 0.0
	type	number
	default	0.0
additionalProperties	False

Scan_type_1.0
