the errmsg string is empty, at least on the output that I've managed
to generate. All I have is the status variable equal to 1, and the
model parameters are within the limits, I checked that first.

A plot of the fit looks OK, and the residuals seem to be fine, so I
suspect it is OK, but the documentation is a bit vague: "STATUS: an
integer status code is returned. All values other than zero can
represent success." So I might be successful, but I'm certainly a bit
uncertain right now ;)
