Notes. We list all of the sources in which a [C i] detection is claimed by Walter et al. (2011), although spectra are currently available for only eight (Fig. 1). These are in order of increasing redshift (z_quoted, which is derived from the centroid frequencies quoted in the reference). ν_ref [GHz] is the frequency given in the reference from which the velocity offset, Δv [km  s^-1], and fitted redshift, z_fitted, are determined. FWHM [km  s^-1] gives the full-width half maximum of the line as determined from the Gaussian fit (all single fits except SMM J16359+6612 for which two Gaussians were used and Δv is the mean of the two fits). The final column gives ΔF/F, in units of 10^-5, derived from the two values of z_fitted.
