IRAC 8 μm image with the marked positions of the identified YSOs. Crosses correspond to objects which are not identified in the JHK_S bands. Diamonds are objects identified only in K_S, squares are objects identified in H and K_S, circles are objects identified in J, H and K_S. Class I objects are in red, class II in green, reddened class II sources in yellow. The dashed box corresponds to the observed SofI field. The contours trace the emission of cold dust at 870 μm from the ATLASGAL survey of the Galactic plane. Contour levels are between 0.5 and 9.5 Jy/beam in steps of 1.0 Jy/beam.
