White light models for WASP-52b transit
Transmission spectroscopy of the inflated exoplanet WASP-52b, and evidence for a bright region on the stellar surface
... Uniform priors were adopted for all the model parameters, with the MCMC walkers started at the values from H´ebrard et al. (2013). The resulting fits of the analytic limb-darkened tran- sit light curves are shown ...
