Note - the green line is the amended (detrended etc) temperature profile, periodic. The blue marks the first year. The green line has 15 year boxcar smoothing, so that when multiplied by a taper, the smooth does not go to zero at the ends.<br><br>
Padded with zeroes to 8192 years. The red lines are the unpadded discrete spectrum<br><br>
M6 is the average of the 6 stations<br><br>
There are three types of detrending, with or without Welch taper. In the table of links below, the first shows all 6 operations on M6. The next 6 show how each operation affects the 7 station groups. Then are shown the 6 stations each  with the 6 operations.
