Table 1: Central coordinates and photometric calibration coefficients for the 7 VLT FORS1 fields as indicated in Fig. 1.
Table 2: Coordinates and photometric properties of the investigated galaxies of the Hydra cluster. The galaxies are ordered by field-number, and within the same field by right ascension. The field number refers to the fields indicated in Fig. 1. Photometry is taken from this paper. (V-I) is from the region where SBF are measured, V₀ is the total magnitude of the galaxy derived from a curve-of-growth analysis. Galaxy numbers, coordinates and radial velocities are from the catalog of Christlein & Zabludoff (2003), except for the NGC galaxy numbers. Galaxy types are according to the morphology on our Hydra images except for the three NGC galaxies, for which the type is from Richter et al. (1989).
Table 3: 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 2001) with an error allowance for $\sigma$ of $\pm$ 0.15 mag is fit to the incompleteness corrected number counts in Fig. 3. 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 2001). 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.
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.
Table 5: The revised SBF distance estimates for the Centaurus cluster galaxies, based on the SBF-measurements from Mieske & Hilker (2003). The first six columns correspond to Table 4 from Mieske & Hilker (2003). The revised columns are those of the newly calculated $\Delta {\rm sim}$ , $\Delta BG$ , $\Delta GC$ , and hence $\overline {m}_{I}$ , (m-M) and linear distance d. We report a typo from Mieske & Hilker (2003): the colour of CCC 75 is (V-I)=1.02 mag, not 1.12 mag.
