GLOSTAR 6.7 GHz emission maps at the velocity of the maser emission peak of the ten strongest new masers, denoted by the magenta ‘X’. Red triangles denote the position of known MMB masers. The flux levels were limited to 75% of the maser peak to better illustrate low intensity features. The white “+” signs show the positions of known compact ATLASGAL sources and the white contours are from the ATLASGAL 870µm dust emission map with contour levels at −3, 3, 5, 7, and 10 σ noise levels.
