Synthetic spectra fits to the CH₃OCH₃ EE lines from the ARO 12 m (top) and Yebes 40 m (middle and bottom). Note that the ARO 12 m transition (the 4_1,4−3_0,3 EE line) was not detected above 3σ and therefore only provides an upper limit. Spectra are offset by 40 mK for easier viewing. The vertical red line is centered at a v_lsr of 3.8 km/s and the gray horizontal lines show the 1σ noise (RMS) level. Only for the 3_1,2 - 3_0,3 transition are the AA and AE+EA torsional states detected above the noise.
