MCMC runs on Gianluca's injected signals:
1.4/1.4 Ms inspiral at
700001930 s (not converged)
1.4/3.5 Ms inspiral at
700002889 s (converged)
1.4/9.0 Ms inspiral at
700004376 s (not converged)
1.4/3.5 Ms inspiral at
700005005 s (converged).
Inclination angle is 45°, and altitude and polarisation are zero for all 4 injections.
Azimuth is 22.5° for the first three and zero for the last one. Coalescence times might be slightly off.

Two illustrations showing the
relation
between inclination & distance.
The left plot shows how the amplitude of a signal with amplitude 1 at distance 1 and inclination pi/2 would change for
different inclinations / distances.
Similarities to these
carvings are probably coincidental.

Updated plots for the MCMC runs on Gianluca's injected signals (only those that converged):
1.4/3.5 Ms inspiral at
700002889 s,
1.4/9.0 Ms inspiral at
700004376 s (this time started from true parameter values),
1.4/3.5 Ms inspiral at
700005005 s .
