Retrieval results with TauREx using a four-point parameterization for the vertical thermal profile. We present four sets ofretrievals. The first set corresponds to the analysis of spectra obtained from the no thermal inversion simulations (light green squares). Then we have three different ways to analyze the spectra from the thermal inversion simulations. The dark green circles show retrievals ignoring TiO and VO, then the light blue triangles and dark blue stars shows retrievals considering TiO and VO without and with condensation, respectively. We plot [CO ]∕[H₂O], [CO ]∕[TiO], [CO ]∕[VO], and the CO, the H₂O, the TiO, the VO abundances within 1σ errors and . These results have been obtained with nonrandomized spectra, but calculations and TauREx assumes a 30 ppm 1σ Gaussian noise on the whole spectral domain. The red line represents the input value in the GCM simulations, and the dashed red line shows where = 1.
