Comparison of CORE, POETS and LBT observations. Upper panel: the gray-scale map reproduces the H₂ 2.12 μm emission observed with LBT toward IRAS 21078+5211. Referring to Fig. 5, lower panel, the blue and red contours have the same meaning, and the yellow contours replace the magenta contours for the JVLA 5 cm continuum. The magenta dashed, white dotted, and cyan dashed lines connect the main 5 cm peak with the secondary (nearby) 5 cm peak, the weak 5 cm spur to NE, and the bow shock traced by the LBT H₂ 2.12 μm emissionto SW, respectively. The white dashed box delimits the region plotted in the lower panel. Lower panel: adaptive-optics assisted LBT observations of the H₂ 2.12 μm emission (gray-scale map): the cyan dashed line has the same meaning as in the upper panel.
