The Exposure-Averaged Point Spread Functions (PSFs) are ~6 MB FITS cubes (one for each detector) with dimensions 101 × 101 × 121. Each of the 121 layers represents a "super-resolution" PSF estimate in a different region (defined by an 11x11 grid) of the detector. Each PSF is a two-dimensional array with size of 101 × 101 pixels. The PSFs are oversampled such that 10 PSF pixels cover the same spatial extent as one spectral image pixel (0.615 arcsec).
