Notes. The key indicates the provenance of the values used in columns two and three, in the order they appear in the table. GSF indicates where the general Schechter function was used rather than the modified Schechter function. Values of ρ_Lyα come from the LAE LF integrated to 0.0006L* (log L_Lyα ∼ 39). T23, dLV19 refer to Thai et al. (2023) and de La Vieuville et al. (2019) respectively.
