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.
Thanks for the bug report,
B
