PSOAP

Precision Spectroscopic Orbits A-Parametrically (pronounced ‘soap’)

PSOAP is a package to model astronomical spectra nonparametrically, for the purposes of disentangling spectra (as in double-lined spectroscopic binaries) or simply determining orbits (in the case of (single-lined spectroscopic binaries or exoplanet hosts). For more information about the mathematical framework underlying PSOAP, please see our paper

Disentangling Time Series Spectra with Gaussian Processes: Applications to Radial Velocity Analysis, Czekala et al., 2017ApJ...840...49C

PSOAP is actively developed on github here
