Fig. 1
Cygnus OB2 image at 325 MHz; the synthesized beam is 7.81′′ × 6.60′′, PA = 88.6°, the rms is 0.2 mJy beam−1, and the intensity peak is 0.270 Jy beam−1. The boxes in the figures show the regions where the proplyd sources studied here lie: source WDDGGHK 10 in box a, WDDGGHK 7, 8, and 9 in box b, WDDGGHK 6 in box c, WDDGGHK 2, 3, and 4 in box d. The white stars mark the position of putative ionizing agents.
