Locations of the OH maser spots, observed with the VLBA, are indicated with small circles. These spots are the same as those plotted in Fig. 1 (also with circles). The asterisk represents the (α, δ)_m point. The groups used to estimate the average velocity (Fig. 8) are indicated with vertical bars. The Argon et al. (2000) OH maser spots are indicated with triangles and the methanol maser cloudlets with crosses (×). All the methanol maser cloudlets that lie in this FOV (Bartkiewicz et al. 2014; Pandian et al. 2011) are on the west side, clumped together near the large dashed circle.
