Assumed spin temperatures and background fractions.

Source Ts (K) Background fraction pbg
GMF20 26 0.75
GMF26 27 0.75
GMF38a 32 0.75
GMF38b 33 0.75
GMF41 37 0.76
GMF54 24 0.77

Notes. The second column gives the spin temperature Ts assumed toward each GMF region. The third column gives the background fraction pbg that is estimated from the ratio of foreground and background column density along the line of sight (see Sect. 3.2.1).
