Mikes Gausian Fit WaveCal (RSG and BSG)

Mike's Email on 6/8/2010 4:39 PM

Hi Carol, Hi Steph,

Today I learned two things:

1.) For a Gaussian fit, FWHM = Width * 2*sqrt(2*ln(2))
where 2*sqrt(2*ln(2)) ~= 1.355

2.) There are two buttons on the PeakFit interface,
called "Fast Peak Fit with Numerical Update", and
"Full Peak Fit with Graphical Update",
and if you don't press one of those buttons
BEFORE you press "Review Peak Fit"
then any gotten via "Review Peak Fit" is preliminary -
good for navigating and setting parameters,
but not a complete fit.

OK, make that three things:

3.) Sometimes it's not a bad idea to RTFM.

With these in mind, I submit a second version of the file
Resonon_WaveCal_fits_2.xls
with what looks to me to be valid Center & FWHM data.

Sorry for the extra work, MF
