Integrated intensities (top), first- (middle) and second -moment (bottom) maps of the H44α radio recombination line are shown in color scale panel. The integration ranges are always from −20 to 20 km s⁻¹. The data were clipped below the 4σ level (Table 1). The contours show the 3.6 mm continuum data on contour levels from 8 to 78 mJy beam⁻¹ (step 10 mJy beam⁻¹). The beam is shown in the bottom left corner of each panel.
