Comparing Gaia, NED and SIMBAD source classifications in nearby galaxies
This study compared Gaia's source classifications against those from literature databases like NED and SIMBAD for sources in nearby galaxies. The findings show Gaia performs best at classifying single stars identified by both databases, but its accuracy drops significantly when classifying background galaxies or quasars. The results indicate that classification performance varies greatly depending on the type of source being studied.
