Star tiles (/starcat/g13/*): positions and G magnitudes of stars brighter than G = 13, derived from
Gaia Data Release 3 (gaiadr3.gaia_source_lite) and repacked into sky tiles for the free, in-browser
plate solver at https://astronomy.sitreps.com/astronomy/atlas. Dense regions keep only the brightest
stars per tile; nothing else is added or changed.

This work has made use of data from the European Space Agency (ESA) mission Gaia
(https://www.cosmos.esa.int/gaia), processed by the Gaia Data Processing and Analysis Consortium
(DPAC, https://www.cosmos.esa.int/web/gaia/dpac/consortium). Funding for the DPAC has been provided by
national institutions, in particular the institutions participating in the Gaia Multilateral Agreement.
