To correct the faulty fitting, two new constraints (marked in the table by a blue square) have been applied. The top one fixes the bulk peak binding energy in the range 98 to 100 eV and the bottom one fixes the oxide peak to a 2 eV wide energy range 3.5 eV above the bulk peak. | To correct the faulty fitting, two new constraints (marked in the table by a blue square) have been applied. The top one fixes the bulk peak binding energy in the range 98 to 100 eV and the bottom one fixes the oxide peak to a 2 eV wide energy range 3.5 eV above the bulk peak. Applying a constraint to a parameter is simple done by writing (using the right notation, of course) in the table - removing is done by deleting. | ||
To apply the constraints on all levels (if several levels are available) one has to | |||
# Click in the upper left corner of the 'Peak Fit' table to select all values and constraints. | |||
# Right click inside the table and select 'Propagate Selected Constraints/Values..' as shown below. | |||
# Select 'All Columns' and 'Constraints and Values' | |||
# Click the 'Peak Fitting' button, select 'Fit All Levels' in the 'Fit Peaks'. | |||
# Click 'Accept' when the fitting routine has completed. | |||
