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.
