Column a: bottom: redshift distribution for the Fe ii* emitters. The grey histogram shows the distribution for the full sample of 271 [O ii] emitters in the redshift range 0.85 < z < 1.50 (271 galaxies), and the red histogram shows the subpopulation of Fe ii* emitters with confidence flag qc > 1 (25 galaxies). White hatching indicates Fe ii* emitters that also have Mg ii emission or P Cygni profiles (9 galaxies). Top: the fraction of Fe ii* emitters for the eight redshift bins. Error bars on these fractions represent 68% confidence levels using Beta distributions as in Cameron (2011). The Fe ii*-emitter fraction is about 10% globally and is also consistent with a uniform distribution. Column b: bottom: redshift distribution for the Mg ii emitters. The grey histogram again shows the distribution for the full sample of [O ii] emitter galaxies, and the blue histogram shows the subpopulation of Mg ii emitters with confidence flag qc > 1 (33 galaxies). White hatching indicates Mg ii emitters that also have Fe ii* emission (9 galaxies). Top: the fraction of Mg ii emitters for each redshift bin with 68% confidence intervals. The Mg ii-emitter fraction is about 12% globally and is also consistent with a uniform distribution.
