Top: molecular maps of H₂O, CO, and full model. The dashed annulus highlights the region considered to quantify the S/N of the detection. The dashed circle represents the position of AF Lep b and is masked for the purpose of quantifying the S/N. Bottom: histograms of the values of the CCF contained in the annular region. The dark line shows the Gaussian fit (with parameters μ and σ shown in the legend), while the orange line shows the value C_p of the CCF at the position of the planet.
