A multi-wavelength study of Galactic H II regions with extended emission (Appendix - Figures)

<p><strong>Regarding figures showing radio continuum and moment-0 maps:&nbsp;</strong>uGMRT radio continuum and GLOSTAR-D moment-0 maps of individual H II regions overlaid with the radio contours from the GLOSTAR-D continuum maps in black. The contours have started at the 3sigma-level flux and have increased in steps of sqrt(3) (G20.99), 2 (G22.76), sqrt(3) (G24.47), sqrt(3) (G25.69), 2 (G27.49), sqrt(3) (G28.30), and sqrt(3) (G28.81), respectively. The coordinates reported in the THOR radio continuum catalog are shown using the green/black '+' signs, while the locations of the UC cores (from the GLOSTAR-B and CORNISH surveys) are shown using the blue '*' signs. The respective beam sizes are shown at the bottom-left/bottom-right corners of the figures.</p> <p>&nbsp;</p> <p><strong>Regarding figures showing peak velocities from GLOSTAR-D RRLs: </strong>RRL peak velocity distribution maps from the GLOSTAR-D data overlaid with the GLOSTAR-D radio continuum contours in black. Starting from the 3sigma-level, the radio contours increase in the multiplicative steps of sqrt(3) (G20.99), 2 (G22.76), sqrt(3) (G24.47), sqrt(3) (G25.69), 2 (G27.49), sqrt(3) (G28.30), and sqrt(3) (G28.81), respectively. The coordinates reported in the THOR radio continuum catalog are shown using black '+' signs, and the respective beam sizes are shown at the bottom-left/bottom-right corner of the figures.</p> <p>&nbsp;</p> <p><strong>Regarding figures showing ionizing stars: </strong>Locations of the candidate ionizing stars (labeled using an S_ _ format) are shown using green '*' signs for the individual H II regions (see Table 4 of the main article for details). The cyan '+' signs indicate the coordinates reported in the THOR radio continuum catalog.</p>
