Notes. The spectroscopic redshifts have been taken from Dawson et al. (2013), Glikman et al. (2011), Marchesi et al. (2016), and Civano et al. (2016). The spectroscopic redshift for UDS10275 has been derived by the Magellan data described in this paper. The X-ray luminosity for the AGNs in the COSMOS field has been taken from Civano et al. (2016). Notes on individual objects: (a)The U band magnitude for this object is not available. (b)COSMOS1710 had a spectroscopic redshift zorig = 3.567 from the work by Marchesi et al. (2016) and Civano et al. (2016), but from our deep FORS2 spectrum we derive an updated spectroscopic redshift of z = 1.547 (see Fig. 8). This object is not included in our final sample where we have measured the LyC escape fraction for AGN at z ≳ 3.6.
