RDs of CO for our targets (continues in 5b and 5c). For each source, the values of T_rot and M_H2 derived from the fits (solid lines) as well as the characteristic radius of the emitting envelope layers adopted (R_CO) are shown (Sect. 5). The errors of T_rot and M_H2 represent the uncertainty of the fit considering the error bars of the individual points, which include formal errors due to the noise and absolute flux uncertainty of the PACS spectra. For a few sources, a double component fit was necessary. For these cases, the values of T_rot and M_H2 for the so-called warm (blue) and hot (red) components are also indicated.
