Abstract (from CDS):

We present observations of 11 quasars, selected in the range z≃2.2-4.1, obtained with ESA's Superconducting Tunnel Junction (STJ) camera on the WHT. Using a single template QSO spectrum, we show that we can determine the redshifts of these objects to about 1%. A follow-up spectroscopic observation of one QSO for which our best-fit redshift (z=2.976) differs significantly from the tentative literature value (z≃2.30) confirms that the latter was incorrect.
