Hi Mailing list,
Well, the chief concern I have with my fit now is that I have some
negative parameters (delr and e0_1):
Guess parameters +/- uncertainties (initial guess):
amp = 0.7709790 +/- 0.0631820
e0 = 1.1165150 +/- 1.0100360
delr = -0.0106440 +/- 0.0077110
ss = 0.0032510 +/- 0.0005200
e0_1 = -4.6848070 +/- 1.7781210
third = 0.0000370 +/- 0.0001070
So, I guess I can drop the third cumulant.
This is a fit using 6 paths (1,2,3,6 are single scatterers)
These are the results this time around:
Reduced Chi-square = 410.285252396
R-factor = 0.014599348
As you can see I am still using two e0's, it is still dramatically improving
the fit. Without: Reduced Chi-square = 1133.485950636
R-factor = 0.044551155
any advice welcomed, Dan
