Hi Andrew!
Indeed, this would be quite useful. I'm thinking of creating a transiting_planet
akin to the known_object
but which is parameterised directly with Tc instead of the mean anomaly phi. This would then work for mono/duo/multi transits in general.
Hi João
That would be great! Let me know if you need a beta-testing volunteer when you get around to implementing it.
Cheers
Andrew

Yes, I could really use the Tc prior capability too for mono/duo transit work.
Hi @accameron, @karenacollins, The ability to set a prior for $T_c$ is now implemented in the new version of kima that can be found here. There is also a worked through example in the documentation.
I will close this issue for now, but please let me know if you run into any issues with the new version.
Thank you!
At present the use of a prior on orbital phase derived from the time of conjunction,Tc, requires the orbital period to be specified as a parameter of make_prior
In the case of a known monotransit planet it would be very useful if users could set a prior on the time of conjunction Tc (say KO_Tcprior) while allowing an uninformative prior on the orbital period, as an alternative to setting a prior on the mean anomaly at the time of the first observation. For any individual sample, phi could then be calculated from the current samples of P, Tc, e and omega.
