Sources identified in the 6 cm image. Those objects shown as white and blue circles have radii of r_obs6 (see Table B.1). Notable Hii regions are indicated. The Hii regions that are masked out for core identification are shown as white contours. The beam size is given in the lower left corner of the main panel (θ_maj, θ_min, PA). The spatial coverage of the 22.4 GHz image is shown as a blue dashed box.
