M 82 frequency survey coverage between 129.8 GHz and 175.0 GHz and between 241.0 GHz and 260.0 GHz. The spectra were smoothed to two channels, corresponding to a channel separation of ~28 km s-1 in the 2 mm atmospheric window and to ~ 18 km s-1 in the 1.3 mm atmospheric window. Species labeled with i-come from the image band.
