VLA C-band (6 cm) continuum emission map of source 48 located in the region IRAS 18228−1312. Three bright peaks are visible and labeled 48a, 48b, and 48c. The green contour levels of the K-band (1.3 cm) continuum emission are 3, 5 and 9 times 0.7 mJy beam^-1. The magenta contours show the Spitzer/GLIMPSE 4.5 μm emission. The pink and green ellipses are the beam sizes of the C and K bands, respectively. The white star marks the location of the H₂O maser (see Table 2).
