Toomre Q map taken from Ahmadi et al. (in prep.) overlaid with the 843 μm continuum contours in white (3, 5, 6, and 7σ) and the water maser locations from Sanna et al. (2012). The water masers are shown with colored crosses where the color represents their radial velocity and for their locations, we use the same naming convention northeast (NE), southeast (SE), and middle-west (MW) as Sanna et al. (2012). The blanked pixel in the Toomre Q map near core A is the assumedlocation of the protostar.
