Hi Bruce,
I figured I'd post this to the Ifeffit list so that others could be
alerted to similar problems, but I'll send you an Athena project file
exhibiting this problem separately, so that everyone's in-boxes don't
get cluttered with attachments.
I'm using Athena 0.8.028 on Windows XP.
First of all, on any file, including the copper data that comes with
Athena, there is a bug. To see it, go to the deglitch screen, and
change Emax by picking a point off the plot. Then replot. From now
on, the green "tolerance" lines extend from Emax up to the end of the
plot, rather than from Emin to Emax. This seems to affect only the
screen display (i.e. it still deglitches the intended range), but it
does make it harder to see what will get deglitched.
The second behavior is best revealed with the project I am sending
you separately. I am not positive it is a bug, but it doesn't match
what I would expect.
In the project I am giving you, the data is very glitchy (lots of
Bragg peaks). Go down to the group labeled SBT/B Bi LIII Merge and
plot in E-space with the post-edge line. Does it look right to you?
It looks like the normalization line is considerably higher than it
should be given the normalization range chosen, with only a few
glitches above it. Is that something I don't understand about the way
the post-edge line is chosen, or is it displaying the line wrong, or
is it calculating it wrong?
Thanks--the new features in Artemis are great, by the way.
