error function in Athena's peak analysis module
Hi every one I am trying to do peak fitting on Athena. Whenever I choose the error function and click "fit" the software crashes, but it works fine when I choose arctangent. Just wondering if anyone encounter the same issue too, and whether I'm missing something during the fitting process. Thanks! Regards Linda
Linda,
I don't know if Athena's strongest feature is peak fitting. It has been discussed before and it might be better to export the processed data and use a more robust fitting program.
buena salud,

Between the recent hurricane and lots of beamtime, I am way behind in addressing the many issues that have come up with the software in the last couple of months. Now that NSLS is no longer in operations, I plan to get back to the software. I will put this on my list of things to do. Thanks for the bug report, Linda. Cheers, B PS: Chris' suggestion is a good one. Peak fitting is certainly not the stringest part of Athena. It's adequate, but not great. It is an area which will certainly benefit by moving from Ifeffit to Larch. On Saturday, November 24, 2012 12:24:08 PM Linda Lim wrote:

This was the result of an easily-fixed typo. The error function will work as advertised in the next release. Thanks again, Linda, for reporting this problem.
