Table 4

Average CO SLED of the (U)LIRGs from P12 that we used here.

J	I _CO ^a	ΔI_CO ^b	N _bands ^c

1	1.00	0.00	14
2	3.59	0.22	13
3	7.11	0.53	14
4	12.4	1.40	6
5	12.2	1.90	0
6	10.6	2.40	14

Notes.

^(a)

Fluxes of individual galaxies have been normalised to CO[1–0].

^(b)

The error is the rms dispersion of individual measurements divided by the square root of the number of galaxies in the sample.

^(c)

Total number of measurements available for the transition from P12. Lacking a direct measurement, we have used an estimate based on LVG modeling of the other available transitions.
