approx(n)
Used in the BCORR 3 module, to choose the way the baseline is estimated.
- 0 : with ITERMA2 times a moving average filtering on a window of size WINMA2.
- 1 : with a Legendre polynomial approximation of degree DEGRE.
- +10 : with a linear interpolation of signal before approximation.
- +100 : with an 'elastic effect' that is a rude way to prevent from burying the weak lines.
