Left panel: stereogram of the CO cube. The blue (red) contours correspond to the velocity-averaged emission profile of the blue-shifted (red-shifted) portion of line outside of the central peak. The contours are drawn at 3, 13, and 23 times the rms noise value outside the line (1.25 × 10⁻³ Jy beam⁻¹). Right panel: the purple and yellow circles show the circular nature of the 3σ_rms emission. The purple and yellow dots represent the centres of the respective circles. The green line (150^° from north, anticlockwise) is the axis along which these circle centres are separated, and therefore the axis along which the system is inclined.
