A partial OpenCL version of the quadratic Mandel-Agol model is also included for GPU-accelerated computations. The aim of PyTransit is to facilitate the analysis of photometric time series of exoplanet transits consisting of hundreds of thousands of datapoints, and of multi-passband transit light curves from spectrophotometric observations, as a part of a researcher&#8217;s programming toolkit for building complex, problem-specific, analyses.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We present a fast and user friendly exoplanet transit light curve modelling package PyTransit, implementing optimised versions of the Gimen&#8217;ez and the Mandel &amp; Agol transit models.
