Abstract:
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.
