Maps of detections of DIB λ5780 (top) and DIBλ6284 (bottom). In the bottom panel, the gray area is the region where EW([O I]λ6300) ≥ 10 Å. The lack of DIBλ6284 detections in these tiles is likely an observational artefact, as the line is blended with the broader [O I]λ6300 feature. The black contours trace the Hα emission and the black crosses show the locations of the AGNs (Komossa et al. 2003).
