Linear LDC for Kepler. The continuous line represents the present calculations by adopting LSM, the dashed line denotes calculations using FCM, and the dashed-dotted line those by Sing (2010). All calculations are based on the Kurucz atmosphere models, with log g = 4.5, log [A/H] = 0.0 and Vξ = 2 km s-1. Right upper corner: observations of I(0) for six extra-solar planetary systems from CoRoT (error bars) and the linear theoretical LDC for CoRoT (same symbols as for the main figure). The full line shows the theoretical LDC computed following Eq. (5). Numbers indicate the CoRoT target star (CoRoT-n).
