I'd like to thank Bruce for reacting so fast to my request for
polarization. (And for fixing the labeling issue.) Sorry for the delay
but I was slowed down by a beamtime and my ancient laptop with 12''
screen. However, thanks to the failure of Lufthansa boarding system I
got plenty of waiting time on my way home and here are the results.
I started tests with the reference data. In the old version I had an
impression that amplitudes of some of the paths are significantly
overestimated. Now their amplitudes are closer to what I expected and
the fitting parameters for them are more reasonable. Parameters for
other paths are more or less the same to what I got from the old version
of Artemis. Seems OK to me.
I noticed few problematic things mainly in the Atoms part of the
program. When I close the project and open it again the list of paths
changes. I am getting some additional paths in polarization. I also
managed to crash the program quite often, usually on the feff
calculations. This does not depend whether the polarization card is
active or not. I will try to investigate it a little bit on a real
computer and will send more detailed report on the problems later.
In summary, the polarization seems to work nicely but one has to be
careful about these additional paths.
