Left: histograms of the effective temperature (top) and surface gravity (bottom) of the models from Exo-REM, reproducing the data, without cloud covering all metallicity values (see text). The number of count is normalized using the invert of the χ². Right: comparison of the best-fit model spectra (dark blue line: best fit, light blue area: 5σ envelope) and of the mesured SED (colored data points).
