Transitions of CH₃C(O)CH₃v = 0 covered by the EMoCA survey. The best-fit LTE synthetic spectrum of CH₃C(O)CH₃v = 0 is displayed in red and overlaid on the observed spectrum of Sgr B2(N2) shown in black. The green synthetic spectrum contains the contributions of all molecules identified in our survey so far, including the species shown in red. The central frequency and width of the frequency range (in parentheses) are indicated in MHz below each panel. The angular resolution (HPBW) is also indicated. The y-axis is labeled in brightness temperature units. The dotted line indicates the 3σ noise level.
