Locations of maser features as derived from the edge-on disk model described in Sect. 5.2, assuming that the masers emerge from the near-side of the disk. Colored dots give the position for features of cluster(s) “A” (left panel) and “B” + “C” (right panel). For each cluster, only the maser features closely aligned along the cluster major axis are considered. Symbols and colors have the same meaning as in Fig. 1. The labeled star marks the YSO position at the disk centre. Dashed arcs indicate circular orbits at steps in radial distance of 500 and 200 AU, for the plot of cluster(s) “A” and ”B” + “C”, respectively.
