Hi,

I am measuring broad spectral lines in iraf, and the problem is that the measurements with deblending in splot and fitprofs do not match. I use the same file as the input, and set the sigma0 and invgain parameters to the same value in both measurements. However, fitprofs gives me much larger errors and in some cases a different wavelength, well out of the error confidence region.

I trust deblending more but I need a non-interactive method.

What might be happening with fitprofs?
