Hi everyone,

I'm doing something like:

yfit = Gaussfit(aar3.data.wave, aar3.data.flux, A)

but sometimes I'm not real happy with the fit it returns:
It uses an A(2), which determines the width of the Gaussian,
which is much too small, fitting the Gaussian through one or
two outlying points. Therefore I want to limit the parameters
A(2) between two values I know in advance. So, does anyone
know whether this is possible and, if so, how to do this?
Thanks in advance,
