Integrated intensity maps between LSR velocities of 141 to 166 km s^-1 (in color) of N 66 for the [ CII ], [ CI ] (³P₁–³P₀), CO (3−2) and ¹³CO (3−2) emission. For comparison, we have superposed the contours of the [ CII ] integrated intensity in black. As in Fig. 1, we have marked the star cluster NGC 346 by a green star, water masers by blue stars, and the supernova by a red star in the top panel. In the CO (3−2) panel we have marked the different components of the N66 structure discussed in the text.
