Correction factor for frequency domain templates.
There's an issue with the normalisation of frequency domain templates when analysing time domain data.
This has been discussed on mattermost and is due to the signal in the data being amplified by a noise power correction factor, but the frequency domain template not being appropriately scaled.
I'm not sure how best to test that this is working. Any suggestions?
The new code was based on [here] (https://git.ligo.org/lscsoft/lalsuite/blob/master/lalinference/src/LALInference.c#L2016) and here.
