Hi Dave,

I'm at the beamline today and will get back to you tomorrow off of the list since this is a rather pointed question at my book chapter.

Hi list,

Doing my first steps in your world, I am trying to model my data. 

I am following Kelly's helpful review from 2008 and stuck on apparently simple 


In order to reduce my deltaE0 (now 9.2), following her advise, I am trying to 

recall the theoretical spectrum from Artemis to Athena; this was produced by 

filtering and fitting my data according to the first shell, then fixing all 

parameters to their best fit, except for enot set to zero, making a sum of all 

paths under these conditions, saving it as a chi(k) and take it to Athena. Here, 

to my understanding, I suppose to introduce the 'new-made' chi(k) as a standard 

and align my data accordingly, save it as a chi(k) and take it back to Artemis

to complete the fitting. Unfortunately I cannot make it a standard in Athena, 

since the whole background options are not available when a chi file is called 


Can someone give a hint? Suggest other ways to better choose E0?
