Improved whitening options for TimeSeries.q_transform
This PR fixes #464 (closed) by improving the default whitening arguments (fftlength
, overlap
, method
) for TimeSeries.q_transform
.
It also adds support for users to supply their own whitening ASD, by passing whiten=fs
where fs
is a gwpy.frequencyseries.FrequencySeries
, as described in the function docstring.
