Notes. The colours of source 2 correspond to a foreground M 5/6 V star whose magnitudes indicate a distance of  ~520 pc. The colours and magnitudes of the remaining 3 sources are inconsistent with any type of stellar source indicating they are heavily reddened, most likely in the Galactic Bulge (see Fig. 10).
