Run CORRECT twice, with STRICT_ABSORPTION_CORRECTION=TRUE and STRICT_ABSORPTION_CORRECTION=FALSE, and compare the results. I find that the anomalous signal in SeMet-SAD/MAD is significantly enhanced in the "Anomal Corr" and the "SigAno" disciplines with STRICT_ABSORPTION_CORRECTION=TRUE (which used to be the default in older versions but is ''not the default since Version May 8, 2007'').
