Notes. From left to right, we list the fiducial values and prior ranges (using 𝒰 to denote a uniform prior) used to simulate the synthetic data for the two cases of stochasticity. The nuisance realizations and the priors are chosen to be either the same or the derived results from Friedrich et al. (2018), Gruen et al. (2018). In our work, the cosmological parameters would be the target ones, while the stochasticity parameters would be the nuisance ones. Ωm, S8 and b have fixed priors and unchanged values for the parameter vectors.
