Posterior probability distribution of the model parameters computed with the likelihood analysis presented in Section 4, from the data of the single mock (mock 0), obtained using two different covariance matrices. Orange: jackknife resampling covariance matrix, and purple: mock covariance matrix corrected with factors proposed by (Hartlap et al. 2006) and (Percival et al. 2014). Dark and light-shaded areas represent 68% and 95% confidence regions, and dashed lines indicate fiducial values of the RSD and AP parameters β and ε.
