Detailed Description

This structure contains a pointer to the collection of sources which will be used to test the PSF model form.

It lists the pmModelType type of model being tests, and contains an element to store the resulting psf representation. In addition, this structure carries the complete collection of FLT (floating parameter) and PSF (fixed parameter) model fits to each of the sources modelFLT and modelPSF. It also contains a mask which is set by the model fitting and psf fitting steps. For each model, the value of the quality metric is stored in the vector metric and the fitted instrumental magnitude is stored in fitMag. The quality metric for the PSF model is the aperture magnitude minus the fitted magnitude for each source. This collection of aperture residuals is examined in the analysis process, and a linear trend of the residual with the inverse object flux (ie, 100:4his structure contains a pointer to the collection of sources which will be used to test the PSF model form. It lists the pmModelType type of modmag) is fitted. The result of this fit is a measured sky bias (systematic error in the sky measured by the fits), an effective infinite-magnitude aperture correction (ApResid), and the scatter of the aperture correction for the ensemble of PSF stars (dApResid). The ultimate metric to intercompare multiple types of PSF models is the value of the aperture correction scatter.

XXX: There are many more members in the SDRS then in the prototype code. I stuck with the prototype code.
