This fitting is clearly wrong and we need to apply some constraints on some of the parameters. Scroll back to a level where all peaks are visible, in this case level 35, see image above. | This fitting is clearly wrong and we need to apply some constraints on some of the parameters.

The Peak Fit table is shown below. The two Si2p spin-orbit doublets (the bulk and the oxide) are referred to as Scan A and B. The various fitting parameters for each of the four peaks are shown in the table along with their constraints. Under each peak is a row with the constraints (in bold) that are to be applied to the parameters. | The Peak Fit table is shown below.
