Integrated emission (in K km s^-1) of the CO⁺ line with the original (11′′, panel A)) and smoothed (16′′, panels B) to D)) angular resolution. In panels A) to D), the gray contour levels range from 40% to 100% in steps of 10% of the intensity peak, where the lower contour level corresponds to a S/N = 5σ. The yellow contour indicates the 3σ emission. The blue squares indicate the IF and MP2 positions, where IF corresponds to α(J2000) = 06h07m46.2s, δ(J2000) = −06°23′08.3′′. panel A) shows the H¹³CO⁺ (3−2) emission (black contours) tracing the molecular gas (Treviño-Morales et al. 2014). Panel B) shows the [Ne ii] emission (red contours) tracing the Hii region and the emission of the H₂ S(3) rotational line at 9.7 μm (black contours). Black contours in panel C) show the PAHs (11.3 μm) emission. Panel D) shows the [Cii] emission at 158 μm (black contours; Pilleri et al. 2014). The Spitzer data are explained in Berné et al. (2009).
