Summary
Accompanies 
to illustrate the impact of increased FFT in the "smoothness" of the spectra and loss of spectral information at the lowest frequencies. Error bars also reduce with the increasing number of FFTs. The green line has been further band-averaged in the frequency domain, which retains the lower frequency data albeit with a reduced frequency resolution (1/3 of 15 FFTs example given 3 frequency bands were averaged).
