Hi Bruce: I have been using the single point deglitching in Athena and I find some strange behavior. It seems that the only thing that counts is the horizontal cross hair. This needs to be right at the vertical position of the point to be selected. The vertical cross hair does not seem to matter. This is sort of counterintuitive and it took me a while to figure out that the program was not just selecting random points on me. Perhaps, if this is a feature of PGPLOT, it should be docmented. I am using the latest version of IFEFFIT and horae on Linux. Carlo -- Carlo U.
