摘要：orbitize! is an open-source, object-oriented software package for fitting the orbits of directly imaged objects.It packages the Orbits for the Impatient (OFTI) algorithm and a parallel-tempered Markov Chain Monte Carlo (MCMC) algorithm into a consistent and intuitive Python API.orbitize! makes it easy to run standard astrometric orbit fits; in less than 10 lines of code, users can read in data, perform one fit using OFTI and another using MCMC, and make two publication-ready figures.Extensive pedagogical tutorials, intended to be navigable by both orbit-fitting novices and seasoned experts, are available on our documentation page.We have designed the orbitize! API to be flexible and easy to use/modify for unique cases.orbitize! was designed by members of the exoplanet imaging community to be a central repository for algorithms, techniques, and know-how developed by this community.We intend for it to continue to expand and change as the field progresses and new techniques are developed, and call for community involvement in this process.Complete and up-to-date documentation is available at orbitize.info, and the source code is available at github.com/sblunt/orbitize.
