** MSC and Mean Centering are also depending on the C-Set spectra selection. NIRCal handles
this dependency automatically. The necessary data is stored in the pretreatments itself so they can
also operate automatically in the predictor of the application.

T: Transmittance or Reflectance
A: Absorbance
S: Spectrum
h: delta X, distance of base point on the x-axis
3.5.3 Normalization
Normalization
The aim of normalization is to reduce baseline variations.
MSC is used to reduce or to increase baseline effects caused by scattering.
Tip
for solids
reduce particle size effects
reduce pressure difference
