Sorry I forgot to put tc & phic in the example.
I modified astroFisherLib.py to include these parameters. Please note that their meaning is that we don't know when the signal happens and at which phase it merges.
It does not mean the time & phase from a reference frequency to the merger. This part is not free to vary because it is fixed by the intrinsic parameters.
It might be good to have a quick scan through the Cutler & Flanagan 94 paper to better understand their physical meanings.
