2.3.2 Make a vp/pb from a polynomial of scaled cosines

Description

A voltage pattern or primary beam of the form

∑ V P(x) = (coefficos2i(scaleix). i

(2.12)

This is a generalization of the WSRT primary beam model.

Arguments


Inputs
telescope	Which telescope in the MS will use this vp/pb?
	allowed:	string
