Hi, i am getting some raman spectroscopy signal,i only found baseline in curve fitting, but is there standalone function to do that. This is because i would like to create a baseline for the background signal and substract it. Will the lowerenvelope function or the spline function helps?

Example:
[code]
Dim _c = Approximation(Signal, APPROX_C + APPROX_X)
Dim approx = Signal(_c[0] + _c[1] * (Signal.X), Signal.X)
Signal – approx
