Zoomed views into designated regions of map shown in Fig. 1, especially to show morphologies and source identifications in crowded and/or fragmented cases. Contours are identical to Fig. 1, marking 5σ (dark green), 10σ, 30σ, 50σ, 70σ (and thereafter increasing by increments of 50σ). Labels correspond to the source identification number in Col. 1 of Table A.1 (where sources are labeled as “serps##”).
