class MultiShapeletBasis
 

Detailed Description

Simple struct that represents one shapelet expansion in a MultiShapeletBasis.

A MultiShapeletBasis is formed by the linear combination of several shapelet bases with different radii and common ellipticity; this represents a single shapelet basis within the MultiShapeletBasis.

Note
This really ought to be an inner class, and should generally be referred to via the MultiShapeletBasis::Component typedef, but Swig doesn't handle inner classes.

Constructor & Destructor Documentation

◆ MultiShapeletBasisComponent()

lsst::shapelet::MultiShapeletBasisComponent::MultiShapeletBasisComponent ( double radius,
int order,
ndarray::Array< double const, 2, 2 > const & matrix )

Main constructor for MultiShapeletBasisComponent.

Should usually only be called by MultiShapeletBasis::addComponent.

Parameters
[in]radiusRadius of the shapelet expansion defined by this component.
[in]orderOrder of the shapelet expansion.
[in]matrixMatrix whose elements [i,j] map MultiShapeletBasis elements j to shapelet terms i; must have dimensions [computeSize(order), basis.getSize()], where "basis" is the MultiShapeletBasis this component is attached to. Will be deep-copied by the constructor.

Note that matrix elements follow the amplitude convention defined by ShapeletFunction; values are proportional to flux, not surface brightness.
