A database of Cepheid distance moduli and tip of the red giant branch, globular cluster luminosity function, planetary nebula luminosity function, and surface brightness fluctuation data useful for distance determinations

We present a compilation of Cepheid distance moduli and data for four secon dary distance indicators that employ stars in the old stellar populations: the planetary nebula luminosity function (PNLF), the globular cluster lumin osity function (GCLF), the tip of the red giant branch (TRGB), and the surf ace brightness fluctuation (SBF) method. The database includes all data pub lished as of 1999 July 15. The main strength of this compilation resides in the fact that all data are on a consistent and homogeneous system: all Cep heid distances are derived using the same calibration of the period-luminos ity relation, the treatment of errors is consistent for all indicators, and measurements that are not considered reliable are excluded. As such, the d atabase is ideal for comparing any of the distance indicators considered, o r for deriving a Cepheid calibration to any secondary distance indicator, s uch as the Tully-Fisher relation, the Type Ia supernovae, or the fundamenta l plane for elliptical galaxies. This task has already been undertaken by F errarese et at, Sakai et al., Kelson et al., and Gibson et al. Specifically the database includes (1) Cepheid distances, extinctions, and metallicitie s; (2) reddened apparent lambda 5007 Angstrom magnitudes of the PNLF cutoff ; (3) reddened apparent magnitudes and colors of the turnover of the GCLF ( in both the V and B bands); (4) reddened apparent magnitudes of the TRGB (i n the I band) and V-I colors at 0.5 mag fainter than the TRGB; and (5) redd ened apparent surface brightness fluctuation magnitudes measured in Kron-Co usin I, K', and K-short, and using the F814W filter with the Hubble Space T elescope (HST) WFPC2. In addition, for every galaxy in the database we give reddening estimates from IRAS/DIRBE as well as H I maps, J2000 coordinates , Hubble and T-type morphological classification, apparent total magnitude in B, and systemic velocity.
