    Yes, a longer abbreviation would be better.  But the "J0459" will be
an invariable portion of the nomenclature, if the source has been given
identifications by other X-ray observations.  This convention has sometimes
been taken especially in abbreviating X-ray sources independently discovered
by multiple satellites.  Anyway, the usage of very ambiguous designations
such as "Tau 3" should be more restricted (I wonder whether people may have
confused this with "3 Tau").
