Notes. The radius of the planet was included as an additional analytic fit-parameter regardless of the model ranging from 0.1 R_J to 2 R_J.

For the initial exploration a wider grid between 1 and 3 was used with a step size of 1. Smaller values were consistently preferred, leading to the final grid values.
