VLA C-band (6 cm) continuum emission map of radio jet candidates 73 and 74 located in the region G23.60+0.0M1. A close-upview of the two radio sources is shown in the bottom panel. The green contour levels of the K-band (1.3 cm) continuum emission are 3, 5, 7, 9, and 11 times 20 μJy beam⁻¹. The magenta contours show the Spitzer/GLIMPSE 4.5 μm emission. The blue- and redshifted outflow lobes of SiO (2−1) are shown as solid blue and dashed red contours, respectively (see Sánchez-Monge et al. 2013b). The pink and green ellipses are the beam sizes of the C and K bands, respectively. The white stars mark the location of the H₂O masers (see Table 2).
