Top left: CO and SiO spectra of the protostellar source #1 of the G328.25 region. On, Off, and On–Off spectra are the black, red, and green spectra respectively. The insets in the top left corner of each spectrum are the signal-to-noise ratio (S/N) for On and On–Off spectra, revealing the significant part of each one. The colored spaces on the spectra are the velocity ranges used to make molecular outflows maps. Bottom left: zoomed-in image on source #1 of the G328.25 region driving a bipolar outflow. The contour colors are the same as in Fig. 3. The CO and SiO contours are 5, 10, 20, and 40 in units of σ, with σ = 60.1, 60.4, 61.9, 62.7 mJy beam⁻¹ km s⁻¹ for CO, and σ = 38.9, 49.0, 38.1, 49.6 mJy beam⁻¹ km s⁻¹ for SiO, for cyan, blue, orange and red contours respectively. Top right: same as top left, but for the prestellar source #6 of the W43-MM1 region. Bottom right: same as bottom left but for the prestellar source #6 of the W43-MM1 region. The CO and SiO contours are 10, 20, 40, and 80 in units of σ, with σ = 32.6, 18.6, 49.5, 15.3 mJy beam⁻¹ km s⁻¹ for CO, and σ = 6.4, 7.4, 7.3, 7.2 mJy beam⁻¹ km s⁻¹ for SiO, for cyan, blue, orange and red contours respectively.
