\caption{\label{resultsgcs}Details of the globular cluster luminosity function (GCLF) fitting for the Hydra galaxies NGC~3309 and NGC~3311 and the Centaurus galaxies NGC~4696 and NGC~4709, performed in the rings where SBF were measured. A Gaussian with width $\sigma=1.3$~mag (Kundu \& Whitmore \cite{Kundu01}) with an error allowance for $\sigma$ of $\pm$ 0.15~mag is fit to the incompleteness corrected number counts in Fig.~\ref{gclf}. The error of the turnover magnitude (TOM) is the maximum of the fitting error and the difference in TOM when changing $\sigma$ to its lower and upper limit of 1.15 and 1.45~mag. $I_{\rm cut}$ is the limiting magnitude for the GCLF fitting, identical to the 50\% completeness limit for GC detection. An absolute turn-over magnitude of $M_I=-8.46 \pm 0.2$~mag is assumed (Kundu \& Whitmore \cite{Kundu01}). The GCLF-TOMs of the two Hydra galaxies are poorly constrained both because of a brighter cutoff magnitude and lower number of GCs compared to NGC~4696.}

\end{tabular}
%For NGC~4696 and 4709, both $\sigma$ and apparent turnover magnitude TOM are fitted simultaneously as the TOM is significantly brighter than the completeness limit. For NGC~3309 and 3311, $\sigma$ is kept fixed at 1.10 mag with an assumed uncertainty of 0.15 mag.
