Notes. Tracer object: AGN – active galactic nuclei, LRG – luminous red giant galaxy, ELG – emission line galaxy, QSO – quasar/quasi-stellar object, LαE – Lyman-α emitting galaxy Columns: btr – linear bias factor of the tracer object; Ωsurvey – solid angle covered by the survey; – surface number density; ⟨ n ⟩ – average volume number density; Veff – effective survey volume at the first BAO peak.
