(a) Overview of superposition of the 1.3 mm continuum (grey dashed contours) and CO (2-1) blueshifted and redshifted (blue and red contours, respectively) emission toward G26. Contours are 3, 5, 10, 20, 30, 40, 50 × 1σ_rms of 0.3 mJy beam⁻¹ for the continuum and 5, 10, 20, 30, 40, 50, 55 × 1σ_rms of 3.0 mJy beam⁻¹ for CO. The redshifted and blueshifted emissions are integrated between 37 and 46 km s⁻¹ and between 7 and 17 km s⁻¹ with respect to the systemic velocity of 24.4 km s⁻¹, respectively. The dashed square marks the region enlarged in (b). The crosses represent the cores labelled with C 1 and C 2, whose parameters are listed in Table 1. The blue and red arrows correspond to tentative directions of bipolar blueshifted and redshifted molecular outflows. The synthesized beam is shown in the bottom left for both images.
