Contour diagram of the mid-transit value of the CLV+RM model of the transmission light curve in a 0.75 Å band for a planet with the same planetary and orbital properties as HD 209458b, but orbiting FGK-type stars from the STAGGER grid. The red dots indicate the grid nodes at which the synthetic spectra were computed. The red star indicates the location of the true HD 209458 star in the grid.
