crop_frequencies called multiple times
Cropping frequencies keeps creating issues (see also #64 (closed)); there seems to be a fix on the horizon (https://github.com/gwpy/gwpy/pull/1621) however whatever the fix, it will probably break what we are doing now. One way to be more robust against this is to (at least) stop calling the cropping functions unnecessarily, hence add checks to see what the actual flow
s and fhigh
s of the spectra are before attempting to crop.
