Table 1:

Properties of the [CII] line observed toward BRI 0952-0115 compared with the CO(5-4) line observed by Guilloteau et al. (1999).
Line	$\nu_{\rm rest}$	$\nu_{\rm obs}$	$z_{\rm line}$	$\Delta V_{\rm FWHM}$	I	$\log(L)^a$
	[GHz]			[km s^-1]	$[\rm Jy~km~s^{-1}]$	[ $L_{\odot}$ ]
[CII] ( $\rm ^2P_{3/2}{-}^2P_{1/2}$ )	1900.54	349.776	$4.4336 \pm 0.0003$	$193 \pm 32$	$33.6 \pm 4.9$	$9.66 \pm 0.25$
CO (5-4)	576.2679	106.055	$4.4337 \pm 0.0006$	$230\pm30$	$0.91 \pm 0.11$	$7.58 \pm 0.25$

^a Log of the luminosity corrected for a lensing magnification of $\mu = 4.5$ , while the error
reflects the possible range in magnifications $\mu =2.5{-}8$ (see Appendix).
