Similar to Fig. 1, but for GRB 050908 (z = 3.3467). The different slit orientations from Table 1 are overplotted. The circle radius of 127 represents the assumed maximum impact parameter of 100 kpc of the intervening sub-DLA at z = 2.6208. Objects are labelled if they lie within the circle and if they are covered by any of the slits. Their magnitudes are summarised in Table 4.
