ultraviolet vs redshift

I got back up to speed on the quasar-photon cross-correlation, splitting the SDSS photometric quasar sample by redshift. This is the first test: Does the ultraviolet flux depend on redshift as we expect? It ought to drop out at the redshifts at which the two GALEX bandpasses cross Lyman-alpha and the Lyman limit. Hope to have results for tomorrow.
