Fig. 5
Position–velocity (PV) diagrams of detected lines of SiO, SiS, and CS main isotopologues. The contours shown in black correspond to 5σ, 2, 10, 50, and 90% of the peak emission (see Table 1 for details). Top: PV diagram of the flux density is shown corresponding to a plane with a declination offset (see Sect. 2) equal to zero. Bottom: PV diagram of the flux density is shown corresponding to a plane with a right ascension offset (see Sect. 2) equal to zero.
