Spectra and maps of 6.7 GHz methanol masers detected using the EVN. The names are the Galactic coordinates of the brightest spots listed in Table 2 (the (0, 0) locations).The colours of circles relate to the LSR velocities as shown in the spectra. Note, that in the first target the scale in distribution is presented in arcsec, while the rest of sources are described by a mas scale. The grey ellipses mark the best-fit ellipses for the sources with the ring-like morphology. The plots for the remaining targets are presented in Appendix A.

This figure is made of several images, please see below:
