¹³CO J = 1−0 integrated intensity contours (black) and 1.4 GHz radio continuum emission contours (blue) overlaid on the Spitzer-IRAC 8 μm emission map (color scale). The black contour levels are 30, 40,..., 90% of the peak value (46.7 K km s^-1). The blue contour levels are 1.7, 3.3, 4.9, 6.5, and 8.1 mJy beam^-1. The letters A and B indicate the different cloud clumps. The green and red crosses indicate four millimeter continuum sources.
