Comparisons Between Observed and Model PSFs in WFPC Image Restoration

J. Mo and R. J. Hanisch


A demonstration of HST WFPC image restoration has been made using both empirical and simulated PSFs. Empirical PSFs are obtained from the WFPC PSF library and also extracted from the image to be restored. Simulated PSFs are generated by the Tiny TIM package. The best results obtained thus far rely upon being able to determine a high S/N empirical PSF from the data frame. In order to achieve accurate restorations of data with high dynamic range excellent PSF models are required. PSF models are less critical when the intrinsic source structure is smooth compared to the size of the PSF.
