Fig. 8

Top: extracted continuum-removed SINFONI spectrum of β Pictoris b with spectral unmixing (dark blue), compared with a BT-Settl model spectrum at 1700 K and log g = 4.0 dex (orange), close to the true planet properties. The first-overtone bandheads of CO are highlighted as being well recovered (shade). The extracted spectrum is not perfect, it is contaminated by unmixed residuals. Bottom: histogram of the residuals (black) with a best-fit Gaussian function (purple).
