G2C2 - I. Homogeneous photometry for galactic globular clusters in SDSS passbands

We present g′ and z′ aperture photometry for 96 Galactic globular clusters, making this the largest homogeneous catalogue of photometry for these objects in the Sloan Digital Sky Survey (SDSS) filter system. For a subset of 56 clusters, we also provide photometry in r′ and i′. We carry out comparisons with previous photometry as well as with the SDSS data set. The data will be useful for a series ...
