Notes. 1) “*” mark the tentative detected molecules. 2) Species except for those marked with “♯” are assumed to have the same temperature (listed in the table head) in the same substructure. 3) Values and uncertainties in bold face are obtained directly from the rotation diagram fittings in Fig. 9. 4) For the species whose transitions are not sufficient to derive the rotation diagrams, their column densities are obtained from one strongest transition by assuming LTE with the excitation temperatures list in the table head (derived from HCOOCH3 for HC, mm2, mm3a, and mm3b). 5) Values of are derived from the temperatures the same as CH3OH list in Table 3. 6) Values of all species in the outflow regions (NE, SR, OF1N, and OF1S) are derived from the temperatures the same as CH3CN at NE. 7) Uncertainties for the values derived from one transition (written as the subscript) are determined from Trot, partition function Q(Trot), and fitting to 
. 8) For species which are not detected, an upper limit derived from 3σ rms is given. 9) “†” mark the values which are likely obtained from optically thick lines and for those we did the optical depth correction.
