Artifacts of the 2MASS database

In the description of the Test of the real 2MASS database (~1/2 billion of point objects) we mentioned that one of the tasks of the 2MASS project was to catalogue all discovered objects.


Testing has shown that 2MASS database contains hundreds of anomalies (defects).

Therefore, not all catalogued points of this base are space objects.
