References. The table provides the source ID, name, and the GLOSTAR in-band spectral index. The observed counterparts in the GLIMPSE 8 μm, MIPSGAL 24 μm, Hi-GAL 70 μm, and the ATLASGAL 870 μm images are marked with a tick (✓). The superscript (*) represents the saturation in the 24 μm MIPSGAL images. The sources having counterparts in the respective catalogs for 8,24 and 70 μm emission, given in Tab. B.2, but not displaying any clear visual signature in the images are represented with the superscript (^c). The ‘Cold dust clumps’ column displays the corresponding cross-matches in either the Hi-GAL 250, 350, and 500 μm bands or the ATLASGAL 870 μm band. The sources occupying the same parameter space in the MIR color–magnitude plot where all of H II regions and a vast majority of the PNe are located, as proposed by Medina et al. (2019), are marked with a tick under the column ‘WISE colors’, and the ones not present in the same parameter space are marked with a cross (✗). The next three columns list the sources with cross-matches with the known, candidate and radio-quiet H II regions from the WISE H II catalog (V2.3; Anderson et al. 2014). The final column represents the classification of these sources as H II regions, and the candidates of H II regions (cH II), Planetary nebulae (cPNe) and Extragalactic sources (cEG). ‘Rad’ represents the unidentified radio sources.
