Table 4: 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.
