4₋₁ → 3₀ E methanol spectra from Maffei 2 (left) and IC 342 (right). Spectra from a given source are all presented with the same amplitude and velocity scale. The adopted rest frequency is 36.169261 GHz, the coordinates are α_J2000 = 2^h41^m552, δ_J2000 = 59° 36′ 12″ (Maffei 2) and α_J2000 = 3^h46^m486, δ_J2000 = 68° 05′ 46″ (IC 342). The velocity scale is the local standard of rest. The spectra were smoothed by averaging 256 contiguous channels to a channel spacing of 9.7 km s⁻¹. The average spectrum was obtained, weighting individual subscans with the inverse square of their system temperature. The systemic local standard of rest velocity for Maffei 2 is –14 ± 5 km s⁻¹ and V_HEL = V_LSR − 3.1 km s⁻¹. For IC 342, the corresponding values are +35 ± 3 km s⁻¹ and V_HEL = V_LSR − 3.9 km s⁻¹. Vertical lines indicating the systemic velocities are included in the lower parts of the averaged spectra.
