Detailed Description

Primary beam envelope class, derived from PBMathInterface.

Intended use:

Public interface

Prerequisite

Etymology

PBMath types do the mathematical operations of the Primary Beamss or Voltage patterns. This envelope class's name was designed for simplicity.

Synopsis

PBMath is an envelope class for the various types of 1D and 2D primary beam/voltage pattern objects. They all have a common interface defined by PBMathInterface. The PBMath object has a counted pointer to the actual PB type; hence, the PBMath object is lightweight and can be passed around by value in other classes.

Construct a PBMath via PBMath's enumerated CommonPB type.

Example

 PBMath wsrtPB(PBMath::WSRT);
 PBMath vla_LPB(PBMath::VLA_L);  // has L band squint built in

A PBMath can also be constructed by the complete argument list for the type of PB it holds. Since different PB types can have the same argument list (PBMath1DPoly and PBMath1DIPoly, for example), the exact type also needs to be specified via the PBMathInterface::PBClass.

The main thing you want to do with a primary beam or voltage pattern is to apply it to an image. The PBMath object forwards its low level "apply" calls to the letter class's "apply" calls.

Example

 PagedImage<Float> in;
 PagedImage<Complex> out;
 MDirection pointingDir(Quantity(135.0, "deg"), Quantity(60.0, "deg"), 
 MDirection::Ref(MDirection::J2000));
 Quantity parallacticAngle(26.5, "deg");
 PBMath wsrtPB(PBMath::WSRT_LOW);
 wsrtPB.applyPB(in, out, pointingDir);   // multiply by primary beam
 wsrtPB.applyPB(in, out, pointingDir, parallacticAngle, BeamSquint::GOFIGURE, 
 True, 0.02); // divide by primary beam
 wsrtPB.applyVP(in, out, pointingDir);   // multiply by voltage pattern

Motivation

This Envelope class allows the user to create a PBMath object which can display all the polymorphic traits of PBMath1D classes or PBMath2D classes.
