CO(3–2) integrated intensity map computed from the unmasked data from –220 to 220 km s⁻¹ for Circinus. The APEX contours are plotted from the masked integrated intensity map in 7 log-spaced levels from 0.36 Jy km/s to 121 Jy km/s. The red contours show the integrated intensity map of the ALMA 12-m array CO(1–0) data from Zschaechner et al. (2016). The 4 contours are plotted on log-spaced intervals, starting at 1.5 Jy/beam km/s to 63 Jy/beam km/s and the edge of the ALMA map is masked to avoid spurious emission from noise. The blue polygon outlines the footprint of the SEST CO(1–0) map of Curran et al. (2008), while the dashed green circle marks the 1′ (1.2 kpc) radius aperture that encloses the bright central region. The beam size of the APEX and ALMA observations is shown in the bottom left.
