Abstract:
We perform a series of comparisons between distance-independent
photometric and spectroscopic properties used in the surface
brightness fluctuation (SBF) and fundamental plane (FP) methods of
early-type galaxy distance estimation. The data are taken from two
recent surveys: the SBF Survey of Galaxy Distances and the Streaming
Motions of Abell Clusters (SMAC) FP survey. We derive a relation
between (V-I)0 colour and Mg2 index using nearly 200 galaxies and
discuss implications for Galactic extinction estimates and early-type
galaxy stellar populations.

Note (1): The PD quality parameter is the product of the seeing in arcsec and
the velocity in units of 1000km/s in the cosmic microwave background
rest frame. It is defined in SBF-II and tabulated in SBF-IV.
