Abstract:	This presentation is devoted to the MEM (Maximum Entropy Method) task, version D, for image restoration in IRAF\@. Described in detail are its enhanced functions of Poisson noise only case handling and subpixelization technique; improved algorithms for maximization including the preconditioned conjugate method, accurate Newton method, the accurate one-dimensional search, and the model updating technique. The task's limitations and possible development are also discussed.
