Algorithm

Iterative/recursive deconvolution is a new image restoration technique developed at the University of North Carolina. The iterative/recursive algorithm is linear, converges rapidly, conserves flux, produces no artifacts and is relatively insensitive to image noise or error in the PSF. It is described in Coggins, Fullton, &Carney (1994a) and in Coggins, Fullton and Carney (1994b, hereafter CFC). In simulations, images deconvolved with this algorithm produced linear photometric results. The intensity of point sources in the restored images was conserved to within 1-2%over a luminosity range of 6 dex (CFC; see also Busko 1994).
