BT-Settl model spectra between 1200 and 2000 K (the range of temperatures where the Bayesian module shows a clear tendency to concentrate predictions around 1600−1800 K) and log   (g) = 5.0. Each panel shows spectra in an interval of temperatures of 200 K. The colour code represents the increment in effective temperature with respect to the lowest temperature covered in the panel. Blue lines correspond to this lowest temperature and red continuous lines correspond to the lowest temperature plus 200 K.
