HE 1029-1831. Top left: the ¹²CO(3–2)/¹²CO(1–0) luminosity ratio with black contours in steps of (4, 6, 8, 10, 12, 14, 16) × 0.1. White contours show the naturally weighted integrated¹²CO(3–2) flux with contours of (4, 8, 16, 32, 48) × 1σ_{rms - int} (=2.0 Jy beam^-1 km s^-1) for a beam size of 3.1′′. Top right: the ¹²CO(3–2)/¹²CO(2–1) luminosity ratio with black contours in steps of (4, 8, 12, 16, 20) × 0.1. White contours show the naturally weighted integrated ¹²CO(3–2) flux with contours of (2, 4, 8, 16, 32, 40) × 1σ_{rms - int} (=2.2 Jy beam^-1 km s^-1) for a beam size of 2.5′′. Left: the ¹²CO(2–1)/¹²CO(1–0) luminosity ratio with black contours in steps of (3,4,5,6,8,10,12,14) × 0.1. White contours show the naturally weighted integrated ¹²CO(2–1) flux with contours of (2, 4, 8, 12, 16, 20, 24) × 1σ_{rms - int} (=0.9 Jy beam^-1 km s^-1) for a beam size of 3.1′′. Gray contours show the naturally weighted integrated ¹²CO(3–2) flux as in Fig. 5.
