simulator.setvp - Function

2.4.1 Set the voltage pattern model for subsequent processing


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. If you are simulating a telescope which doesn’t yet exist, you will need to supply a model voltage pattern using the vpmanager.

Arguments
