[Ifeffit] Question on GDS values: amp

[Nicholas.Tse at csiro.au]

Dear All,

Just wondering what could I do to make the amp guess value as a positive number? If I run it and let it float (i.e. guess), the amp becomes negative in the resulting fits, but the fit has nice delr and ss values (i.e. make sense). If I restrict the amp value to 1, everything else doesn't fit. I am only fitting the first nearest neighbour in a measured standard; Gadolinium oxide.

Regards,

Nic
