vpmanager.setpbcospoly

Make a vp/pb from a polynomial of scaled cosines

Synopsis setpbcospoly(telescope, othertelescope, dopb, coeff, scale, maxrad, reffreq, isthispb, squintdir, squintreffreq, dosquint, paincrement, usesymmetricbeam)

Description A voltage pattern or primary beam of the form

VP(x) = $\displaystyle \sum_{i}^{}$ (coeff_icos²ⁱ(scale_ix).

(1.20)

This is a generalization of the WSRT primary beam model.

Arguments

`telescope`	Which telescope in the MS will use this vp/pb?
	`Allowed:`	`String`
`othertelescope`	If telescope=="OTHER", specify name here
	`Allowed:`	`String`
`dopb`	Should we apply the vp/pb to this telescope's data?
	`Allowed:`	`Bool`
	`Default:`	`T`
`coeff`	Vector of coefficients of cosines
	`Allowed:`	`Vector of Double`
	`Default:`	`0`
`scale`	Vector of scale factors of cosines
	`Allowed:`	`Vector od Doubles`
	`Default:`	`0`
`maxrad`	Maximum radial extent of the vp/pb (scales with 1/freq)
	`Allowed:`	`Quantity`
	`Default:`	`0.8deg`
`reffreq`	Frequency at which maxrad is specified
	`Allowed:`	`Quantity`
	`Default:`	`1GHz`
`isthispb`	Do these parameters describe a PB or a VP?
	`Allowed:`	`String: 'PB'\|'VP'`
`squintdir`	Offset of RR beam from pointing center, azel frame (scales with 1/freq)
	`Allowed:`	`Measure`
	`Default:`	`Measure`
`squintreffreq`	Frequency at which the squint is specified
	`Allowed:`	`Quantity`
	`Default:`	`1GHz`
`dosquint`	Enable the natural beam squint found in the common vp model
	`Allowed:`	`Bool`
	`Default:`	`F`
`paincrement`	Increment in Parallactic Angle for asymmetric (ie, squinted) vp application
	`Allowed:`	`Quantity`
	`Default:`	`360deg`
`usesymmetricbeam`	Not currently used
	`Allowed:`	`Bool`
	`Default:`	`F`
