Notes. Grouped here are sources with a continuum detection and angular separation within a GLOSTAR beam. From left to right: source number and YSO Galactic coordinates from Nandakumar et al. (2018). The Galactic coordinates of the pixel with the peak intensity of the 5.8 GHz continuum (this work), the peak intensity (Sp), the integrated flux density (Sint) and error (δSi; Purcell et al. 2013), and the spectral index (α). The effective diameter of the source (Deff) was obtained by assuming a circle with an equivalent area to the area enclosed by the contour used for flux determination. The separation indicates the angular distance between the reported YSO position in Nandakumar et al. (2018) and the peak intensity position of the radio continuum source where we are constrained by the pixel size (2.5″). The root-mean-square (rms) indicates the noise level that was obtained from a nearby emission-free patch. The general morphology (Qshape) of the source is classified as compact (C), extended (E), and extended & complicated (EC). Previous classifications and detections (catalogues) include WISE candidate (WC), radio quiet (WQ), group (WG), or known H II regions for nearby sources (WK; all Anderson et al. 2014), as well as sources with counterparts in the NVSS survey (Condon et al. 1998), Becker et al. (1994), or ATLASGAL (Sánchez Contreras et al. 2017).

(a)

Despite the slightly larger separation, the YSO lies well within the main 5.8 GHz emission peak.

(b)

Associated to the ‘20 km s−1 cloud’.
