Application of ForMoSA using the BT-SETTL15 models. Top: bimodal posterior distribution. Bottom left and right: comparison of the best fit and the observed data for the low T_eff and high T_eff modes. The data points were obtained using the low-resolution SPHERE-IFS spectrum (R ≃ 30–50; blue points, Chauvin et al. 2017), the SPHERE-IRDIS H-band photometry (green and red points; Cheetham et al. 2019), our medium-resolution SINFONI spectrum (R ≃ 5500); orange points, this work), and the NaCo L’ and M’-band photometry (purple and brown points, respectively; Cheetham et al. 2019). We overlaid 50 synthetic spectra picked randomly within the 1σ envelop of each posterior in gray.
