Historical Research Notes / Correction for NGC 4649
NGC 4649 = M 60. See NGC 4637. - Dr. Harold G. Corwin, Jr.
Correction Disclaimer
As with all corrections to the NGC and IC Catalogues, there is a certain margin for error, even though the evidence supporting the correction may be strong and compelling. It is with this in mind that we ask the user to use this information as 'Most Probable', but never to assume the correction is 'Absolute'. All published corrections are based on an exhaustive 'paper chase' of the historical record back to the original discoverer's published notes/papers, and are therefore based upon the historical accuracy (or inaccuracy) of those particular notes/papers. In short, Caveat Emptor! - Robert E. Erdmann, Jr.
