Line-integrated map of the ¹²CO(1−0) transition from the BIMA-SONG sample. The yellow points show the observed GREAT positions in IC 342. The (0, 0) position corresponds to (RA, Dec) (J2000) (03:46:48.5 68:05:47). The red points indicate named GMCs and other structures according to Table 3 in Meier & Turner (2001). Triangles facing up and right indicate H II regions and super nova remnants, respectively, as given by Tsai et al. (2006). The [C II] and [N II] spectra are shown on the right side. The [N II] intensity scale is multiplied by a factor of 5.
