Moment maps of the ¹²CO(1 → 0) (left) and ¹³CO(1 → 0) emission (right) of the mIVC integrated between −45.8 km s^-1 ≲ v_LSR ≲ −33.1 km s^-1. Before integration, the data cubes are masked using a spatially and spectrally smoothed version of the data cube as a mask. The contours mark the modelled dust optical depth from Planck from 1 × 10^-6 to 9 × 10^-6 in steps of 2 × 10^-6. The beam-sizes are plotted at the bottom left corner.
