Ionized emission associated with the H IIregions – panels a and b: 610 and 1280 MHz maps for the region associated with G346.056−0.021; panels c and d: 610 and 1280 MHz emission for the region around G346.077−0.056. The contourlevels are 3, 5, 10, 15, 20, 25, 30, and 35 times σ, where σ is equal to 0.3 mJy beam⁻¹ and 0.2 mJybeam⁻¹ at 610 MHz and 1280 MHz, respectively. Beam in each band is shown as filled ellipse. These maps are generated by setting the “robustness parameter” to −5 and withoutany uv tapering.
