Mean Centering
The mean spectrum of the C-Set spectra will be subtracted from each spectra, only the deviation is
remaining.
NOTE
Do not use Mean Centering as the last step in the pretreatment sequence when the Mean Centering
has already been activated in the Calculation Parameters dialog box.
The Mean Centering defined in the Calculation Parameters box is calculated directly after the
pretreatment sequence.
Type
This pretreatment is not depending on the calibration wavelengths.
Subtract spectrum
When selecting this pretreatment the number of the spectrum, which should be subtracted from the
other spectra, has to be entered.
In this way it is possible to enhance the differences in the data set.
NOTE
The scale factor can also be negative to add a spectrum.
