Comparison of the absolute positions of the identified radio continuum compact sources (C1–9, see Table 4) and those of the water maser components M1 and M2 (see Table 3). The plus symbols “+” indicate the compact sources while the star symbol is centred at the position of M1, (the dimensions of the map do not allow us to discern M1 from M2, and for this reason the point is denoted M). The sizes of the symbols do not correspond to the absolute position uncertainties.
