Abhijeet,

I took a quick peak at your project and I find it very confusing. In
the most recent fit, you are fitting only from 3.5 to 4.4 -- the area
under the *third* peak in the data. I don't really know how to
comment on this project because you have set a large number of
parameters to seemingly arbitrary values. From a numerical
perspective, the reason for questions 1 and 2 is because you are
attempting to fit only a narrow and of the data and you have set the
majority of your parameters. That seems an unlikely strategy to me.

I think the best thing you could do would be to fit *all* of your data
rather than an arbitrary and small band of it.

It would probably be fruitful for you to study carefully Shelly's
example of analysis of SnO2 from her recent review chapter. See

Hello Bruce sir,

Thanks for your response. You must be talking about the 14th chapter of the book "Soil and Mineral analysis using XAS". I have that chapter with me. It is very explainatory one.

with regards

Abhijeet
