Abstract:

We discuss the application of the Pixon Based Image Restoration Method on spectroscopic HST data and compare the results with those obtained from the Richardson-Lucy and Jansson algorithms. In order to better evaluate the performance of the various algorithms we have also used artificial data.

Keywords: Spectral restorations, Pixons, Richardson-lucy, Jansson
