wobble is an open-source python package for analyzing time-series spectra. It was designed with stabilized extreme precision radial velocity (EPRV) spectrographs in mind, but is highly flexible and extensible to a variety of applications. It takes a data-driven approach to deriving radial velocities and requires no a priori knowledge of the stellar spectrum or telluric features.
wobble is under development.
To install the current developer version:
git clone https://github.com/megbedell/wobble.git cd wobble python setup.py install
