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.
