Detailed Description

pmPSF data structure

It is useful to generate a model to define the point-spread-function which describes the flux distribution for unresolved sources in an image. In general, the PSF varies with position in the image. We allow any of the source models defined for the pmModel to represent the PSF. For a given source model, the 2D spatial variation of all of the source parameters, except the first four PSF-independent parameters, are represented as polynomial, stored in a psArray. The other elements of the structure define the quality of the PSF determination.
