KIMA

kima is the name of a really good drink produced in Azores And now, it's also a package for the analysis of radial velocity (RV) data... At its core, kima fits Keplerian curves to a set of RV measurements, using the Diffusive Nested Sampling algorithm 1 to sample the posterior distribution for the model parameters. Additionally, the code can calculate the fully marginalized likelihood (or evidence, ZZ Z) of a model with a given number of Keplerians and also infer the number (Np N_pN p​) of Keplerian signals detected in a given dataset. In this case, Np N_pN p​ is a free parameter in the fit and its posterior distribution is estimated 2, 3.
