Notes. The measurements are all derived from the spectroscopic data cube. The quantity T, is the brightness temperature of the continuum (at 250 and 200 GHz), as defined in Eq. (8). The parameter α is the local continuum power-law index of the brightness temperature, computed between 210 and 290 GHz for the 250 GHz case, and between 165 and 220 GHz for the 200 GHz case. In both cases, the CO and H2O lines are excluded from the continuum fit. The integrated line intensity, I, and the effective EW, EW, as defined respectively by Eqs. (10) and (11), are given for the CO(2-1) and H2O transitions. Systematic uncertainties arising from bandpass errors are not included in the table.
