Cross-correlation functions of COCONUTS-2 b NIRSpec spectra (at full resolution) with H2O, CO, CH4, CO2, NH3, and PH3 molecular templates generated using petitRADTRANS. The S/N was computed using formula (1) of Houllé et al. (2021). Upper panel: CCFs obtained using the NRS1 detector where H2O, CH4, and NH3 are detected. Lower panel: CCFs obtained using the NRS2 detector where H2O, CO, CH4, and CO2 are detected.
