Comparison of the SIDES [CII] LFs with ALPINE observations. Top panel: ALPINE data at z ∼ 4.5, bottom panel: ALPINE data at z ∼ 5.5. In both panels, the black solid line corresponds to the total Uchuu field LF and the dashed line corresponds to the median LF of 54 2 deg² SIDES-Uchuu subfields. The shaded areas are the 16th–84th and 5th–95th percentile intervals while the red line is the SIDES-Bolshoi LF (B22). The blue and green points are the data from Yan et al. (2020), while the black square is the data point from Loiacono et al. (2021).
