Same as Fig. 5, but for CO(2−1) (top) and CO(3−2) (bottom). The black dotted line present at z > 3 indicates the CO(2−1) LF derived in SPRITZ considering the steepest extrapolation considered for the number density (i.e. Φ* ∝ (1 + z)−4). Bo20 and Es22 refer to the relations by Boogaard et al. (2020) and Esposito et al. (2022), respectively.
