Hello, Since I haven't received a response to my previous question, I just wanted to make sure I asked it clearly. To elaborate, I am attaching a log from Athena. The log file lists:
"Independent points = 27.057617188"
If I attempt to reproduce this result using the equation in the feffit
document, I find
Nidp = { [2*(kmax - kmin)*(Rmax-Rmin) / pi] + 2} = { [2*(14 - 0.5)*(4.2 -
1.0) / pi] + 2} = 29.50197417,
where I have used the k-range and R-range in the log file as kmax, kmin,
Rmax, and Rmin.
Can someone explain to me why may calculation does not reproduce the number
given for "independent points" in the log fie?
Thank you,
George
