* If I don't rebin the data, Athena will not choose the point which I am
intend to remove (I think i have some minor issues here). If I rebin the
data from ~ 2400 to 350 points, Athena will work correctly.*

*I mentioned "MOVE" in my above sentence, (Just to be more specific, when I
double click on the plot to choose a point, sometimes Athena select its own
random points away from the point where I clicked, when I try to drag that
randomly chosen cursor to the point of my interest, it will not work), IS
THIS NORMAL?  *

*I will try to figure out all the possible ways for non-rebinned data, if
it does not work at least for now rebinned data works.*

Hmm.  I don't really understand why that would be.  Anybody else see this?
Do you find that you need to re-bin by a factor of 7?

It's news to me that you can move a point on the graph at all. I
thought you could only remove it or not.  Anybody else know anything
about this?

I'm sort of stumped.  Do you see this behavior with other data sets as
well or just this particular set?  Is re-binning always the solution?
