Abstract:

The model updating technique used in the Maximum Entropy Method (MEM) task for image restoration in IRAF/STSDAS is described in detail. The properties of the method, including faster convergence in iteration and reduced nonlinearity of the solution in photometry, are discussed and shown by statistics and illustrations.

Keywords: entropy, Maximum Entropy Method, image restoration, IRAF, photometry
