Investigations of the detection performances using the molecular mapping. Upper left and right: CO molecular maps obtained following the injection of a simulated planet at ρ = 812 mas and PA = 165.2° in the original datacubes using Exo-REM models at T_eff = 1650 K, log(g) = 4.0 dex, [M/H] = 0.0,and C/O = 0.35 and 0.70 at a velocity of 30 km s⁻¹. Bottom left: histograms of CCF values at a velocity of 30 km s⁻¹. Bottom right: CCF obtained at the position of the simulated planet.
