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.
Hi Carlo, That behavior is not my intention for the single point deglitching. I actually try hard to select the closest point to the center of the crosshair in that situation. I'll look into it. I should mention that there are some situations in Athena where it only considers the position of the *vertical* crosshair. For example, if you pluck a value for, say, kmin from a chi(k) plot after clicking one of those little blue-X buttons, Athena uses the x-coordinate chosen from the plot rather than the x-coordinate of the point closest to the center of the crosshair. That seems sensible to me in that case. But I do agree that for deglitching, choosing the position of the horizontal cross hair would be screwy. I'll let you know what I find.
