 Smoothing 
  For example, "3" is the command for a medianofthree smooth and "H" is the command for Hanning. 
  At the first appearance of a comma, the smoothed sequence will be saved, to be replaced (temporarily) by its "rough", which is the series of residuals (differences between the original and smoothed values). 
  The smoothed value at location i in the series x[1], x[2],..., x[N] is the middle value of {x[iK], x[iK+1],..., x[i+K]}, provided iK >= 1 and i+K <= N. Otherwise, the smoothed value is the original value (except for medians of three).
