Hi,
I am an undergraduate student from Wuhan University and I am currently doing a project about GW with some waveforms without spin such as EccentricFD. I noticed that when there’s no prior about spin(eg. a_1, a_2 or chi_1, chi_2.) the parallel bilby likely still generates a prior for processing spin BBH event with tilt_1, tilt_2, and other parameters is related to precession. It confuses me and I wonder whether I need just to set them even when they are useless parameters for these waveforms, or do I need to use bilby instead of pbilby?
Thanks.
