Setting a prior on the period for a duo-transit

[soleneulmer]

For a planet with two non-consecutive transits, we have a set of possible orbital periods. For the transiting planet , could we have a prior which reflects this information (e.g. a set of Gaussians around the possible periods) ?

[j-faria]

There is a new GaussianMixture distribution and a helper function to create it from two T0 values:

kima.pykima.utils.get_prior_monotransits(T0_1, T0_2, T0_1_err=0.1, T0_2_err=0.1, lower_limit=1.0)

I haven't tested it extensively, so let me know if something doesn't work.
