A new version of this important southern-hemisphere Sloan uvgriz photometry catalogue has been announced:
https://arxiv.org/abs/2008.10359
...and is now searchable from their main Web site (linked in the URL above). This extends the flter coverage and depth, as well as removing the zonal zero-point problems in DR1 inherited from APASS. Most of the southern sky is now covered at Sloan i and z.
