	Package	synthesis
	Module	map
	Tool	calibrationmanager

Create a voltage pattern calibration data item

Synopsis
vp(usedefaultvp, vptable, dosquint, parangleinc)

Arguments

usedefaultvp		Look up the default VP for this telescope and frequency?
		Allowed:	Bool
		Default:	T
vptable		If usedefaultvp is false, provide a VP Table made with vpmanager
		Allowed:	String
dosquint		Activate the beam squint in the VP model
		Allowed:	Bool
		Default:	True
parangleinc		Parallactice angle increment for squint application
		Allowed:	Quantity
		Default:	360deg

Returns
calibration data item
or fail

Description

This function creates a voltage pattern calibration data item from either a default beam response, or from a voltage pattern table created by the vpmanager. This image-plane correction is applied during imaging; especially in mosaicing.

Example

mycm:= calibrationmanager();
item1:= mycm.vp(usedefaultvp=T, dosquint=F);

Create a calibration data item item1 representing default voltage pattern calibration with the squint term disabled.
