Hi!

Thanks for the FAQ tip. And yes, MPFIT2DFUN, looks just right for the job.

Furthermore, I used IDL's own CURVEFIT for an earlier (1-d) fit. I guess I
could use it in principle also here, but was seeking for a more intuitive
(for me) approach. However I was puzzled with the error estimates I got
for the parameters (they just don't make sense). If I understood what I
have read from the documentations thus far, MPFIT seems to addresses this
problem also.

Cheers,

Esa
