Fig. 4
MALT90 spectra of sources A, B and C, whose positions are represented in Fig. 9 with “A” (l = 332.693, b = −0.610), “B” (l = 332.677, b = −0.619) and “C” (l = 332.645, b = −0.608), respectively. The red dashed lines indicate the peak velocities of the C18O emission. The green curves are Gauss-fit lines. HCN and N2H+ have hyperfine splitting, shown as a black bar.
