Spectra (black) of the quasars discovered in the vicinity of cluster ext#2. In red a quasar template is overplotted. Objects a and b can be regarded as cluster members or rather active galaxies in the cluster outskirts. Object c is an unrelated distant X-ray luminous quasar serendipitously found in this study (Lamer et al. 2011). The labels correspond to the objects identified in Fig. 8. Spectral features, etc., are coded as in Fig. 6(c). In the case of a the emission lines are Lyα and CIV.
