Channel maps of the 12CO J = 1−0 and J = 2−1 emissions (in contours) toward IRAS 19475+3119 at the LSR velocities (units of km s-1) specified in the top-left corner of each panel. In the background, in grey scale, the optical image obtained by (Sahai et al. 2007b) is shown for comparison. No primary beam attenuation correction is applied. (Top) CO J = 1−0: contours are plotted from and with a spacing of 2.8σ, where σ =  6.9 mJy beam-1. Equivalent negative contours are plotted with dashed lines. Contours presenting relative minima in the CSE are plotted in grey (red in the electronic version). The synthesized beam is at PA = 17°, and is drawn in the bottom-right corner of the last panel. No continuum emission is detected with a σ = 0.4 mJy beam-1. (Bottom) CO J = 2−1: contours are plotted from 6σ, with a spacing of 3σ, where σ =  11 mJy beam-1. In the panels marked with c in the bottom-left corner an additional contour is plotted at 3σ. Equivalent negative contours are plotted in dashed lines. Contours presenting relative minima in the CSE are plotted in grey (red in the electronic version). The synthesized beam shown in the bottom-right corner of the last panel measures 0″̣8 × 0″̣5 with PA = 14°. No continuum emission is detected with a σ of 0.6 mJy beam-1. The central coordinates are RA 19:49:29.561, Dec 31:27:16.29 (J2000).
