Notes. 

(a)

The nomenclature follows the one presented by Downes etal.(1992, their Fig. 1). Component B is not seen in ammonia.

(b)

Sdv (Jy K km s-1).

(c)

There is  ~1 mJy of absorption in the NH3 (2, 2) line toward source B of Maffei 2 in the velocity range between −20 and 100 km s-1. Since this absorption is at the edge of our band we did not fit a Gaussian to it.
