[Ifeffit] background fitting functions in Artemis

[Chris Patridge]

Hello all,

If a background is difficult to remove due to short paths lengths, can a 
background fitting be used in the Artemis fit?  I have a large data 
range giving near two times the ind points even when including the 
background function.  After fitting the data, it gave a number of 
correlations some of which are negative.  The parameters give reasonable 
values and uncertainties and I feel confident about the model.  I know 
the fit is not great but can I use this as the starting point or is the 
background just giving me a large fudge factor?

Thank you,

Chris Patridge
