Equations for the analysis of the light curves of extra-solar planetary transits

The argument in Eq. ( Equation ( In these equations, denotes an auxiliary angle so that the true anomaly can be reckoned from the centre of the transit. As mentioned in the paper, this angle is shown in Fig. In case of circular orbits there is of course no difference between and the orbital phase. Fortran subroutines for the computation of light curves and the Rossiter effect, simultaneously, are available at http://thor.ieec.uab.es/LRVCode/
