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 develop

The paper presenting the wobble method used a slightly older version of the code than what is currently in the master branch. To access this version, install wobble and then change branches:

git checkout paper-version
