CO ﹩J=1{\mbox{--}} 0﹩ channel maps and 2.6 mm continuum map of IRAS 19475+3119 obtained at OVRO. Each panel for the CO line covers a velocity bin of width 2.6 km s−1, centered at the LSR velocity shown near the top left corner. Contour levels are as follows: (1) for the CO line, positive contours run from 2 σ in 3 σ steps; and negative contours run from −2 σ in −3 σ steps, where ﹩\sigma =40﹩ mJy beam−1 is the rms noise; (2) for the continuum contours run from 2 σ in 1 σ steps, where ﹩\sigma =0.9﹩ mJy beam−1. The cross is located at the tracking center of the observations (﹩\alpha _{\mathrm{J}\,2000.0}=19^{\mathrm{h}\,}49^{\mathrm{m}\,}29.74^{\mathrm{s}\,}﹩, ﹩\delta _{\mathrm{J}\,2000.0}=31^{\circ }27^{\prime }16.33^{\prime \prime }﹩). The peak of the CO emission is located at ﹩\alpha _{\mathrm{J}\,2000.0}=19^{\mathrm{h}\,}49^{\mathrm{m}\,}29.56^{\mathrm{s}\,}﹩, ﹩\delta _{\mathrm{J}\,2000.0}=31^{\circ }27^{\prime }16.1^{\prime \prime }﹩.
