35.            #so you have to lie.  Tell it the sample rate is
54.            #1000 Hz, then scale in your head.
29.            #For example, 1000Hz --> 1.0 cycles/year
21.            #              500Hz --> 0.5 cycles/year
11.            #              100Hz --> 0.1 cycles/year

3.    #year 1710    #The largest peak in the sunspot spectra occurs at
0.            #91Hz on our scale --> 0.091 cycle/year, more commonly
0.            #known as the 11 year sunspot cycle.
