Dimethyl ether integrated intensity maps obtained with the Plateau de Bure Interferometer: these panels show the sum of the emission of the transitions at 80.54 GHz, 101.56 GHz, 203.42 GHz and 223.41 GHz. The first contour and the step are 0.5 Jy/beam, 0.2 Jy/beam, 2 Jy/beam and 0.3 Jy/beam at 80.54 GHz, 101.56 GHz, 203.42 GHz and 223.41 GHz respectively. Note that the 203.42 GHz transitions are blended with the HO line at 203.407 GHz around (α_J2000 = 05^h35^m145, δ_J2000 = −05°22′34″). The BN object position is (α_J2000 = 05^h35^m141094, δ_J2000 = −05°22′22724), the radio source I position is (α_J2000 = 05^h35^m145141, δ_J2000 = −05°22′30575), and the IR source n position is (α_J2000 = 05^h35^m143571, δ_J2000 = −05°22′32719) from Goddi et al. (2011).
