Equivalent width distribution function per unit redshift of the MAGG Mg II absorption line systems (orange pentagons). The 10th and 90th percentiles from the bootstrap resampling and the width of each bin of equivalent width are shown as vertical and horizontal error bars, respectively. The results for the MAGG sample are consistent with the completeness-corrected functions from Zhu & Ménard (2013) (black solid line) and Chen et al. (2017) (purple dots) down to W_r ≈ 0.1 Å.
