Ml-phare underestimates occupancy of SIRAS weak anomalous signal. This is usuallu of no significance, as such signal is useless anyway. I did number of tests that show that siginificant anomalous signal in SIRAS is estimated reasonably. One should take a note that patterson may look nice even for a poor signal and opposite. -- Zbyszek Otwinowski | zbyszek@chop.swmed.edu University of Texas | tel : (214)-648-5098 Southwestern Medical Center | fax : (214)-648-5095 5323 Harry Hines Boulevard Dallas, Texas 75235-9038 [EOB]
