Quadratic LDCs determined by MCMC for our high signal-to-noise target sample (see Table 1). For comparison, the graphs show model predictions based on PHOENIX (solid) and ATLAS (dashed) atmospheric models, taken from Claret & Bloemen (2011). The dotted lines show Claret and Bloemen’s LDCs determined for the same atmospheres by different methods (see Sect. 5.1). The diamond symbol indicates TrES-2, which has the highest impact parameter of this sample (b = 0.845). Triangles mark conspicuous objects, discussed in Sect. 5.3.
