Spectra of each of the measured lines. The Mopra data, both SiO lines and the CH3OH70−61+ 44 GHz Class I line, have spectral resolution 3.6 km s-1 and channel spacing 1.8 km s-1. The ATCA data have spectral resolution 1.9 and 1.4 km s-1 and beam shapes 4.85″ × 1.49″ and 9.4″ × 0.46″ for the H2CO and CH3OH lines, respectively.
