ln(s)

I will see to it that this will be indicated in the plot.

Hi Peter:

One more thing.

The plot in figure, is that "Signal vs b"  or "Ln(Signal) vs b" ?

Thanks

-Anil

Dear Anil,

If I look at the code, the method actually does a 3-parameter LM fit:

I am not sure where the output on the clipboard originates from.

Do you know anything about this, Michael & Paul?

Peter

I have been using IVIM module to determine f, D and D* using 3-parameter fit.
However, when I copy measurement points to excel, I see that it does first 
linear fit of D and f at high b, and then, fits for D*.  Should this not do
3 parameters simultaneously using L-M method when I choose option of 
3-parameter fit?

Appreciate your answer.
