Overlay of the radio continuum emission toward the HMC in G16.59−0.05 at 6 cm (red contours), 2 cm (green), 1.3 cm B-array (blue), and 1.3 cm A-array (gray scale). The contour levels range, respectively, from 0.0264 to 0.1584 in steps of 0.0264 mJy beam^-1, from 0.03 to 0.09 in steps of 0.03 mJy beam^-1, from 0.174 to 0.348 in steps of 0.058 mJy beam^-1, and from 0.075 to 0.25 in steps of 0.025 mJy beam^-1. The solid circles and empty triangles represent, respectively, the CH₃OH and H₂O masers from S2010, while the arrows are the proper motions of the H₂O masers. The scale for the proper motion amplitude is given on the bottom left of the panel. The size of the VLA beams for the different array configurations and wavelengths are reported in Table 1.
