  The radial-velocity (RV) method is one of the most successful in the
detection of exoplanets, but is hindered by the intrinsic RV variations of the
star, which can easily mimic or hide true planetary signals. kima is a package
for the detection and characterization of exoplanets using RV data. It fits a
sum of Keplerian curves to a timeseries of RV measurements and calculates the
evidence for models with a fixed number Np of Keplerian signals, or after
marginalising over Np. Moreover, kima can use a GP with a quasi-periodic kernel
as a noise model, to deal with activity-induced signals. The hyperparameters of
the GP are inferred together with the orbital parameters. The code is written
in C++, but includes a helper Python package, pykima, which facilitates the
analysis of the results.
