\caption{\label{resultstab}Result of the SBF measurements for the investigated Hydra
cluster galaxies. The error in metric distance $d$ is the mean of the 
upper and lower distance error range
corresponding to the magnitude error in $(m-M)$. 
The columns $ZP$, $\Delta {\rm sim}$, $\Delta BG$, $\Delta GC$, $\overline{m}_{I}$ and $(m-M)$ are given in magnitudes.
For the two giant galaxies NGC~3309 and NGC~3311, the results shown are the averaged means over the three rings
investigated. In the lowest row, the mean distance $d$ and the corresponding distance
modulus $(m-M)$ of all galaxies are given. }
