This VAC contains the eBOSS large-scale structure catalogues for DR16 quasars (QSOs), and consists of the data and randoms catalogues that underpin the cosmological analyses from the eBOSS team. These catalogues contain all the data and necessary information (window function, systematic quantities, completeness estimates and corrections for close-pairs and redshift failures) to reproduce the team's clustering measurements. The VAC is described in detail in Ross et al. (2020), and on the website linked above.
Older versions of this VAC based on previous data releases are still available, and linked on the website above. We always recommend that you use the latest version of this VAC.
