Plot showing the process of smoothing the BSG laser data. I used an SSA to smooth the data with 20 modes. The smoothed data is the sum of the first two modes. As you can see in the figures below for most of the laser data the first mode is nearly 98% or more of the variablility. I already had code which removed the main peak, reflection peak and secondary peak prior to smoothing. This helps the SSA modes to focus on the noise rather than trying to "fit" the peaks. The main peak and reflection peaks dont really need smoothing anyway.
