Hi,
The easiest constraint would be a mathematical expression such as "a + b = 1".
Do you have an experimental value for so2 as found for something chemically
similar such as a standard at that edge? Then replace so2 expression for each
path as "value found * a" and "value found * b". This sh

In Artemis and in Ifeffit, a "constraint" is a mathematical relation
between parameters. A "restraint" is a math e
I wanted to add that you need a reasonable measure of confidence that these are
the only paths contributing because otherwise you could receive negative
values for a or b in the fit results if there are other paths involved by using
this simple constraint.

Dear All,
I am trying to fit the first FT shell in Artemis with a mixture of two
different compounds (octahedral and tetrahedral models). I would like
to quantify the ratio between this two compounds in my sample so I
decided to multiply So2 by a parameter called "a" in one model and by
