petitRADTRANS best-fit spectrum of 51 Eri b for the 'enforced clouds' retrieval run on our new SPHERE spectro-photometric data (teal circles and purple squares) along with the photometric points included in Samland et al. (2017) (shown as squares). The photometric points describe the average flux in the respective filter, the x-error bar represents the filter widths. 34 randomly drawn samples from the posterior probability distribution are shown in gray, to show the spread of model parameter combinations to fit the data. Residuals in multiples of 1σ uncertainties of the data are shown below.
