Conditional [C II] LF from the M25 (dashed lines) and M50 (solid lines) simulations at redshifts z = 5 and 3 for central galaxies (left panels), satellites galaxies (middle panels), and all galaxies (right panels). The coloured lines show the CLF of emitters residing in DM halos in different M_halo bins and the black lines show the total LFs. The dotted grey line in the right panels denotes the luminosity threshold, L_thr, below which the total LFs from two simulations differ significantly due to resolution effects.
