Table 8: Emission in CO and H  I by the sample galaxies. Both the fluxes and the errors are in units of 10⁵⁴ W km (Hz s)^-1 for CO, and of 10⁵² W km (Hz s)^-1 for H  I. The error column corresponds to the photometric error and does not take into account the uncertainty in the distance. In some cases, no error estimate is given for the H  I emission because this was not given in the literature. A hyphen (-) means that no data are available.
