Notes.

(a)

The error in TMB includes the  ~15% calibration uncertainty (see the text in Sect. 3.1).

(b)

τm is the optical thickness of the (1,1) main group. The total optical thickness, i.e., the sum over all satellites, is τtot = 2 × τm.

(c)

TMB(1,1) was determined by substracting the second velocity component from the spectrum.
