| Abstract: |
We report on the status of a two channel photometric restoration technique and its current implementation as an IRAF task called GIRA. This method is particularly suited to stellar photometric measurements in crowded fields or in images where an extended structured background is present. The current implementation allows the use of several analytical point-spread-functions, or the image of an empirical PSF. When an analytical PSF is used, the program can automatically adjust the positions of input objects to improve the fit to the observed data. |
