Baseline Methods

AirPls	Adaptive Iteratively Reweighted Penalized Least Squares (AirPls) baseline correction.
ArPls	Asymmetrically Reweighted Penalized Least Squares (ArPLS) baseline correction.
AsLs	Asymmetric Least Squares (AsLs) baseline correction.
ConstantBaselineCorrection	A transformer that corrects a baseline by subtracting a constant value.
CubicSplineCorrection	A transformer that corrects a baseline by subtracting a cubic spline through the points defined by the indices.
LinearCorrection	A transformer that corrects a baseline by subtracting a linear baseline through the initial and final points of the spectrum.
NonNegative	A transformer that sets all negative values to zero or to abs.
PolynomialCorrection	A transformer that subtracts a polynomial baseline from the input data.
SubtractReference	A transformer that subtracts a reference spectrum from the input data.
