\caption{\label{tab:r0amps}Present-day spatial correlation lengths and $1\sigma$ errors derived from the 
galaxy \acf ($\gamma=1.8$) of the NVSS as a function of flux density limit. Listed are the results found using two 
different cosmological models and two different values for the evolution parameter $\epsilon$ (see text for details).}
