Upper panels: radio continuum emission distribution at 1.4 GHz (left panel) and 4.85 GHz (right panel). Contour levels for the 1.4 GHz image go from 21 mJy beam^-1 to 42 mJy beam^-1 in steps of 7 mJy beam^-1 and from 60 mJy beam^-1 in steps of 10 mJy beam^-1. For the 4.85 GHz data the lowest contour level is 40 mJy beam^-1 and the contour spacing is 20 mJy beam^-1. Black crosses indicate the positions of WR 55 and HD 117797. Lower panel: overlay of the radiocontinuum emission at 1.4 GHz and 4.85 GHz on the Hα emission of RCW 78.
