K_p−Δυ_sγs maps for the non-detected species. Left panels: emission model of each species with the wavelengths covered by CRIRES+ K2166 setting used in this work shown as vertical grey bands. Middle and right panels: the detection maps for the pre-ecl., post-ecl., and combined nights of the CRIRES+ data (Sect. 3.4). The high-resolution opacities were obtained from the following sources: ¹³CO, CO₂ and OH from the HITEMP line list (Rothman et al. 2010), metal opacities from (Kurucz 2018) and HCN opacities from ExoMol database (Harris et al. 2006; Barber et al. 2014).
