Channel maps of H₂O masers in H₂O(B) (SVS 13C) and V512 Per (SVS 13A). The contours start at 0.5 Jy, and then increase by a factor of two. The plus signs represent the positions of the two H₂O masers (orange and green) previously detected by Haschick et al. (1980) and YSOs (purple; e.g. Plunkett et al. 2013). Based on previous observations (Plunkett et al. 2013; Podio et al. 2021), the outflow directions are indicated by red and blue arrows. The beam size is shown in the lower right corner of the last panel. The colour bar represents the flux density in units of Jy.
