G2C2 I: Homogeneous SDSS photometry for Galactic GCs

Abstract

We present $g^{\prime }$ and $z^{\prime }$ aperture photometry for 96 Galactic Globular Clusters, making this the largest homogeneous catalog of photometry for these objects in the SDSS filter system. For a subset of 56 clusters we also provide photometry in $r^{\prime }$ and $i^{\prime }$. We carry out comparisons with previous photometry as well as with the SDSS dataset. The data will be useful for a series of applications in Galactic and extragalactic astrophysics. Future papers will analyse the colour-metallicity relation, colour-magnitude diagrams, and structural parameters. The compilation of results based on this dataset will be collected in the Galactic Globular Cluster Catalog (G2C2).
