Notes.

^(a)

Partially blended with CH₃OD (E, 5₀ → 4₀) in the blue wing. However, to map the CH₃OCH₃ emission, we avoided the contribution of CH₃OD by selecting an appropriate interval of velocities (see Fig. C.1).

^(b)

Cernicharo et al. (2016).

^(c)

Partially blended with the red wing of a CH₂DCN line (14_{6, 8} → 13_{6, 7} & 14_{6, 9} → 13_{6, 8}) in the EG and ET peaks.

^(d)

Tercero et al. (2015).

^(e)

Blended with the red wing of a U line at 228408 MHz (assuming a v_LSR of 7.5 km s⁻¹) in the EG and ET peaks.

^(f)

Tercero et al. (2015); partially blended with some emission from extreme velocities of ³⁴SO₂ (6_{3, 3} → 6_{2, 4}) and SO₂ (26_{3, 23} → 25_{4, 22}) in the EG and ET peaks. Nevertheless, the emission at MF peak is not blended (see Fig. C.1).

^(g)

Blended with some emission from extreme velocities of SO¹⁸O (12_{1, 12} → 11_{0, 11}), CH₂DCN (13_{8, 5} → 12_{8, 4} & 13_{8, 6} → 12_{8, 5}), and HCOOH (10_{3, 7} → 9_{3, 6}) in the EG and ET peaks. Nevertheless, the emission at MF peak is not blended (see Fig. C.1).

Blended with some emission from extreme velocities of NH₂CHO (11_{2, 10} → 10_{2, 9}) in the EG and ET peaks.
