HCN 3–2 and HCO⁺ 3–2 for IRAS 09022−3615. Left panels: (Top two panels) Spectra extracted from the resolved aperture. (Lower two panels) Spectra extracted from the global aperture. Velocities are relative to the systemic velocity. The corresponding velocities of potentially detected species are indicated by vertical dotted lines. Right panels: (Top) Integrated intensity over ±500 km s⁻¹ (moment 0). Contours are (5, 10, 20, 40, 80, 120, 160, 200) ×σ, where σ is 0.020 Jy km s⁻¹ beam⁻¹. (Second from top) Velocity field (moment 1). Contours are in steps of ±50 km s⁻¹. (Third from top) Velocity dispersion (moment 2). Contours are in steps of 20 km s⁻¹. Moment 1 and 2 were derived with 3σ clipping. (Bottom) $L_{\text{HCN}}^{\prime }/L_{{\text{HCO}}^{\text{+}}}^{\prime }$. Color scale is from 0.285 to 3.5. Overlaid ellipses represent the apertures used for spectral extraction. Solid and dashed lines represent the kinematic major and minor axes, respectively. The synthesized beam is indicated by hatched ellipses in the lower right corners.
