Notes. (a)We use the GOT C+ naming convention to identify the LOSs (Langer et al. 2010; Goldsmith et al. 2015). (b)Rgal is calculated using the approach described in Pineda et al. (2019, see Sect. 3.2). (c)If there are temperature solutions to more than one component we use an average value. (d)The 1σ error for the integral. (e)The errors include those due to uncertainties in I(205 μm) and Tth (K). (f)The solutions to n(e) and N(N+) derived in Goldsmith et al. (2015). (g)An accurate value of Tth could not be derived (see Table 4) and we adopt the value from G026.1+0.0 for this LOS.
