Abstract:
We present new photometry for 323 of the globular clusters in NGC 5128
(Centaurus A), measured for the first time in the g'r'i'z' filter
system. The color indices are calibrated directly to standard stars in
the g'r'i'z' system and are used to establish the fiducial mean colors
for the blue and red (low and high metallicity) globular cluster
sequences. We also use previously published spectroscopically measured
abundances to establish the conversion between the most
metallicity-sensitive colors ((g'-r')0,(g'-i')0) and metallicity,
[Fe/H].
Description:
Imaging of the NGC 5128 field was taken over five consecutive nights
in May 2008, in the SDSS griz filters, with the Yale/SMARTS 1.0m
telescope at the Cerro Tololo Inter-American Observatory, Chile.
