A raw spectrum is given, see the figure below.

Plot the four spectra below (raw, baseline subtracted, and two smoothed spectra) onto one plot offsetting each from the other by a vertical offset of 2.0. Label in some way. (colour with legend?). (a) Remove any baseline that may be in this spectrum. (b) Using the baseline subtracted spectrum: Create the spectrum (i) after applying a 3 channel boxcar average smoothing and (ii) after applying a (standard 3 channel) Hanning smoothing.. (c) What is the noise in each of the smoothed spectra in (b)?
