Some uses include:\n\n* Fitting for radial velocities in a template-free manner\n* Inferring orbits of single-lined spectroscopic binaries (e.g., exoplanets/their host stars)\n* Generation of high-fidelity stellar templates (for use with traditional RV cross-correlation measurements, variability searches)\n* Inferring orbits and spectra of double-lined spectroscopic binaries (see gif below)\n\nDocumentation and installation instructi\nons are available at [http://psoap.readthedocs.io](http://psoap.readthedocs.io).\n\n![disentangling loop](output.gif \"disentangling loop\")\n\nIf you use our paper, code, or a derivative of it in your research, we would really appreciate a citation to [Czekala et al. 2017](http://adsabs.harvard.edu/abs/2017ApJ...840...49C):\n\n    @ARTICLE{2017ApJ...840...49C,\n        author = {{Czekala}, I. and {Mandel}, K.~S. and {Andrews}, S.~M. and {Dittmann}, J.~A. and\n        {Ghosh}, S.~K. and {Montet}, B.~T. and {Newton}, E.~R.},\n        title = \"{Disentangling Time-series Spectra with Gaussian Processes: Applications to Radial Velocity Analysis}\",\n        journal = {\\apj},\n        archivePrefix = \"arXiv\",\n        eprint = {1702.05652},\n        primaryClass = \"astro-ph.SR\",\n        keywords = {binaries: spectroscopic, celestial mechanics, stars: fundamental parameters, stars: individual: LP661-13, techniques: radial velocities, techniques: spectroscopic},\n         year = 2017,\n        month = may,\n        volume = 840,\n          eid = {49},\n        pages = {49},\n          doi = {10.3847/1538-4357/aa6aab},\n        adsurl = {http://adsabs.harvard.edu/abs/2017ApJ...840...49C},\n        adsnote = {Provided by the SAO/NASA Astrophysics Data System}\n    }\n\nCopyright Ian Czekala and collaborators 2016-17.\n\n## Papers using PSOAP\n\n* *Disentangling Time-series Spectra with Gaussian Processes: Applications to Radial Velocity Analysis*, [Czekala et al. 2017](http://adsabs.harvard.edu/abs/2017ApJ...840...49C)\n* *The Architecture of the GW Ori Young Triple Star System and Its Disk: Dynamical Masses, Mutual Inclinations, and Recurrent Eclipses*, [Czekala et al. 2017](http://adsabs.harvard.edu/abs/2017arXiv171003153C)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fiancze%2Fpsoap","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fiancze%2Fpsoap","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fiancze%2Fpsoap/lists"}
