Function Documentation

pmModel* pmModelFromPSF (  pmModel *  model, pmPSF *  psf )

This function constructs a pmModel instance based on the pmPSF description of the PSF. The input is a pmModel with at least the values of the centroid coordinates (possibly normalization if this is needed) defined. The values of the PSF-dependent parameters are specified for the specific realization based on the coordinates of the object. Parameters: model  Add comment psf  Add comment

pmPSF* pmPSFAlloc (  pmModelType  type  )

Allocator for the pmPSF structure. Parameters: type  Add comment

bool pmPSFFromModels (  pmPSF *  psf, psArray *  models, psVector *  mask )

This function takes a collection of pmModel fitted models from across a single image and builds a pmPSF representation of the PSF. The input array of model fits may consist of entries to be ignored (noted by a non-zero mask entry). The analysis of the models fits a 2D polynomial for each parameter to the collection of model parameters as a function of position (and normalization?). In this process, some of the input models may be marked as outliers and excluded from the fit. These elements will be marked with a specific mask value (1 == PSFTRY_MASK_OUTLIER). Parameters: psf  Add comment models  Add comment mask  Add comment
