The TABULAR option reads in a dataset created by the CREPSF
application (see Section 6.8). The psf system uses the MASK
parameter to read in the name of the dataset,
PSF - Choose PSF to use for source model /'WFC'/ > TABULAR MASK - Name of a 2D dataset containing psf > POINT_SFThe AUX parameter is not used. Note that the psf system does not check that the binning of the tabular psf is compatible with an image being searched or background subtracted. The solution to this shortcoming is not simple, as there are occasions when the binning does not matter, and the TABULAR psf routine has insufficient information to decide this.
