[Ifeffit] Chi in arthemis

[Eugenio Otal]

Hi Scott,
here I copy a part of the report:

Independent points          =       6.222656250
Number of variables         =       4.000000000
Chi-square                  =     247.145092496
Reduced Chi-square          =     111.193574128
R-factor                    =       0.017422216

Guess parameters +/- uncertainties  (initial guess):
  amp             =     6.7815290   +/-      1.4687660    (1.0000)
  enot            =     2.2173620   +/-      2.1499920    (0.0000)
  delr            =     0.0514640   +/-      0.0163900    (0.0000)
  ss              =     0.0074020   +/-      0.0025220    (0.0030)

I see that the R-factor is pretty good, 1.74%, amp is high cause is
correlated with the coordination number and always have big errors., delr
has the error of the total distance, so it is ok, but ss and enot have a a
really big error, is this normal?
Thanks, euG
