| Smoothing |
 | | For example, "3" is the command for a median-of-three 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[i-K], x[i-K+1],..., x[i+K]}, provided i-K >= 1 and i+K <= N. Otherwise, the smoothed value is the original value (except for medians of three). |
