I am new to NCL and used the 'specxy_anal' script to read in two time
series to calculate their cospectra as well as phase and coherence
spectra. In terms of analysis of the results, I was wondering if
anyone knew how exactly these spectra are calculated, especially the
phase and coherence, or where I can find information on this?

In the script this is only stated as :

'spec = specxy_anal(time series 1,time series 2, d, sm, pct)'

whereby 'spec_anal' calculates everything; phase, coherence etc. are
only attributes of 'spec' for which no further details are shown.

d, sm, pct only refer to detrending, smoothing and tapering of the series

Any help appreciated,
