In this context, we also compare the results of using the atmospheric retrieval code \\texttt{petitRADTRANS} vs a self-consistent model to fit atmospheric parameters. We present a higher signal-to-noise $YH$ spectrum of the planet and revised $K1K2$ photometry (M$_{K1} = 15.11 \\pm 0.04$ mag, M$_{K2} = 17.11 \\pm 0.38$ mag).
