Redshift evolution of the observed UV luminosity density (not corrected for dust). Our points are shown in black and are compared to various rest-frame UV LFs available in the literature at different redshifts. All the points are derived by integrating the rest-frame UV LFs down to ﹩{M}_{\mathrm{UV}}=-13﹩, and the errors on the points are estimated using the uncertainties in the LF parameters as reported by the individual references.
