In the fitting parameters screen, I am not able to constrain areas to a certain range. If I input a range for the areas to be limited to, the area parameters simply go out of range every time I attempt to fit the peaks to the data. Has anyone else experienced this issue or discovered a fix for it? Also, please do not use the fitting uploaded with this post. It is incomplete and likely inaccurate.

Growth in RTA @800°C by 290s, then etching, this data corresponds to the last etching at 1800s. ARXPS 0-65°

Fitting of the Ge 3d photoemission spectrum for a single crystal surface, data were published by Lawson et al. (accession #0032903). The spectrum was fitted employing one Voigt doublet. The branching ratio was forced to be equal to the theoretically expected value (0.6865), which was taken from the Scofield tables.
