K_p-v_sys matrices of S∕N values for the ExoMol TOTO model, as described in Sect. 3.3. Each panel corresponds to the matrix for a different SVD iteration (0–5), indicated above each panel. The strongest peak is marked on each matrix with a cyan ring and noted above each panel with the corresponding values of K_p and v_sys. The dashed cyan box indicates the region where peaks must be found to be considered “significant,” as described in Sect. 4.
