Merge branch 'antenna-patterns' of gitlab.aei.uni-hannover.de:einsteinathome/pulsatingscience into antenna-patterns

I am assuming that the initial lower frequency is 30 Hz.  Need to check code in this
respect.

DIFFERENCES between those at the different detectors.  So to
make for a less confusing visual display in the GUI, I have
offset the output phase as a function of psi, in a way that
tries to reduce confusion about the meaining of the orbital
coalescence phase.

Not sure why a merge is needed, could be that OB fixed things twice, once on my laptop, then once in GIT

Normalizing phase to LLO produced a misleading behavior when changing the orientation of LLO. Shifted relative phases to a more sensible convention

Add some frequency and amplitude modulation to the plot
