Zacharias, Norbert; McCallon, Howard L.; Kopan, Eugene; Cutri, Roc M., 2000, "Extending the ICRF into the infrared : 2MASS - UCAC astrometry", https://hdl.handle.net/2014/40162, IAU XXC, Joint Discussion 16 : The International Celestial Reference System, Maintenance and Future Realizations, Sydney, Australia, July 22, 2003., JPL Open Repository
An external comparison between the infrared 2MASS and the optical UCAC positions was performed, both being on the same system, the ICRS. About 48 million sources in common were identified. Random errors of the 2MASS catalog positions are about 60 to 70 mas per coordinate for the... |
