Tool qimager


Set the voltage pattern model for subsequent processing


Synopsis
setvp(dovp, usedefaultvp, vptable, dosquint, parangleinc)


Description
Set the voltage pattern model (and hence, the primary beam) used for a Telecope. There are currently two ways to set the voltage pattern: by using the extensive list of defaults which the system knows about, or by creating a voltage pattern description with the vpmanager. The default voltage patterns include both a high and a low frequency VP for the WSRT, a VP for each observing band at the AT, several VP's for the VLA, including the approrpiate beam squint for each observing band, and Gaussian for the BIMA dishes. Due to temporary limitations in the internal structure of the visibility buffer, only one telescope's voltage pattern can be applied to a particular MeasurementSet. This will be corrected shortly.



Arguments

dovp Do voltage pattern (ie, primary beam) correction
Allowed: Bool
Default: F
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: F
parangleinc Parallactice angle increment for squint application
Allowed: Quantity
Default: 360deg


Returns
Bool


Example
- imgr.setvp(dovp=T, usedefaultvp=T, dosquint=F);
