Parameter correlation plots for my fit using ellc to the radial velocity data and light curves of the eclipsing binary J0113+31 from Gómez Maqueo Chew et al. (2014, GMC+2014). The adopted parameter values from GMC+2014 are indicated by lines/points in each panel. The contours in each panel show the 0.5-, 1-, 1.5- and 2-sigma confidence regions for each joint parameter distributions. Points outside the 2-sigma confidence region are individual steps from the emcee MCMC chain.
