| Notes for designation: This is the object sequence designation, or object "name" as specified by the IAU recommendations on source nomenclature. It is derived from the J2000 sexigesimal coordinates of the source and has the form HHMMSSS+/-DDMMSS, where HH are the hours of right ascension, MM the RA minutes and SSS are the deci-seconds of RA. DD are the degrees in declination, MM are DEC minutes and SS the declination seconds. Note that both the RA deci-seconds of time and DEC seconds of arc are truncated rather than rounded, per the IAU recommendation. | |||||||||
