We compare the populations of candidate stars, white dwarfs, galaxies, and AGNs identified by the ClassX classifiers among the unclassified X-ray sources from the Rosat All-Sky Survey with the previously known populations of these objects. The candidates are on average fainter, and apparently include more distant representatives of respective object types. We examine their X-ray properties along with the optical, infrared, and radio properties where available in order to detect any differences between the newly identified and previously classified sources. Using ClassX classification probabilities, we isolate the most reliable candidates among each of the object types and assess efficiency of the ClassX classifiers in terms of the fractions of reliably identified sources.
