Evolution of the comoving VEM at rest-frame 840 Å vs. redshift for the redshift intervals z = 0.65–0.95 and z = 0.95–1.15 (blue open squares show the directly measured values, and solid squares show the incompleteness corrected values). We also show the evolution determined by CBT09 from measuring the GALEX FUV magnitudes of an X-ray-selected sample (red diamonds). For each point, the x-axis error bars show the redshift interval and the y-axis error bars show the 1σ error computed using the jackknife method.
