I had an Athena project with some references loaded as chi(k)-data and some unknown samples as chi(k) as well. Athena won't let me start the Linear Fit-Dialog stating that it (she) needs at least three xmu-spectra. Changing the preference to "standard fit in k-space" does not help. Workaround: I just loaded some dummy xmu-Spektra and can now work with the dialog.
Also, only these xmu-spectra can be selected from the "standards pluck boxes", the only way to insert the chi(k)-references is to use "use marked groups". That is a bit of a problem when you have to move one of the groups up because its value is negative. Workaround is to move up the groups in in Data group section.
Hmm... it seems that I had not done any testing with chi(k) records as standards. There are several problems. Thanks for pointing this out.
- Is there any possibility to plot the linear fit and the data in R-space right away? (without first saving it as a datagroup)
That can be done. Good idea.
- It would be nice to be able to store the relative weigths together with the newly created dataset.
I don't really understand this. The results of the LCF fit are saved as title lines for the new data group, but you must be looking for something else.
