Total [Oii] flux distributions for the five Fisher and the CC_UGRI selections. The vertical dashed line represents the approximate of objects with S/N = 3. Objects with unreliable [Oii] flux measurement are represented at . We consider here only those galaxies with a reliable z_spec measurement. Top panel: eboss6-7 galaxies. Middle panel: VIPERS galaxies for the Fisher selections. Bottom panel: VIPERS galaxies for the colour–colour selections. We report the Fisher_UGRIZW1 selection to facilitate the comparison.
