Dear Mike and Dave: Thanks for your help. I have one more very basic question: -using plot_bsub_counts from .isisrc, if I choose popt.res=5, I got a Y axis in the residuals panel that has a \chi^2 label. Is this defined exactly as the delchi command in XSPEC, whose label is \Delta\sigma \chi^2?, what are the units of the ISIS's delchi definition?. I'm asking because I saw that Sherpa also add a different label with the delchi command. Thanks a lot Juan ######################################################## GERARDO JUAN MANUEL LUNA Instituto de Astronomia, Geofisica e Ciencias Atmosfericas Universidade de Sao Paulo Brasil 05508-900 ######################################################## __________________________________________________ Preguntá.
