There are 3 standard designations for sources detected in observations made with the Chandra X-ray Observatory.
CXO is reserved for use by the Chandra X-ray Observatory Center (CXC) for designating sources from projects of an institutional nature.
CXOAA, CXOAAA, and CXOAAAA (i.e., "CXO" with two, three, or four appended characters) are available for comprehensive source lists derived from Chandra observations and made by individuals who pre-register the acronym using the IAU form at http://cdsweb.u-strasbg.fr/viz-bin/DicForm where they indicate the meaning of the appended characters, which are usually the initials of the author(s).
CXOU where U means "unregistered" may be used for the occasional sources found/published by individuals using Chandra X-ray Observatory data.
