PSF file and format for SkyMaker

RE: PSF file and format for SkyMaker
(sorry for the insane delay in answering this post). Unfortunately SkyMaker does not have any documentation, and I don't see how I could find the time to write one in the foreseable future Rolleyes. You may use an external tabulated PSF model stored as a mypsf.fits (basic) FITS file using the following command-line arguments: -PSF_TYPE FILE -PSF_NAME mypsf.fits. mypsf.fits should contain a generously sampled (4+ pixels / FWHM) image of the PSF, centered in the frame. It is advised to use an image with an odd number of pixels on each axis to avoid confusion. The PSF_OVERSAMP configuration keyword should be used to specify the oversampling factor; the most recent versions of SkyMaker support non-integer oversampling factors.
