This VAC contains 1000 realizations of synthetic clustering catalogues, constructed using the effective Zel'dovich approximation mock generator (EZmock; Chuang et al. 2015), for each type of the tracers used for the baryon acoustic oscillation and redshift space distortion analysis of eBOSS DR16. This mocks cover a redshift range from 0.6 to 2.2, for reliable estimates of covariances matrices and test the robustness of the analysis pipeline with respect to observational systematics.
For more details on the construction of this VAC, and the clustering properties of the EZMock catalogs, please see Zhao et al. (2021).
