The gray-scale background is the Herschel 160 \(\mu\)m map, and the gray and white contours correspond to A\(_V\) = 5 and 10 in the 2MASS/NICEST near-infrared extinction map, respectively. The red circles represent two particular sources: the one on the left is L1689B, and the one on the right is IRAS16293. The scale bar on the bottom left is 0.1 pc.
