For reference, the … Only some minor corrections have been included in our online database. Effects of metallicity, star-formation conditions, and evolution in B and Be stars. Its designation in the New General Catalogue is NGC 581. Some objects originally thought to be deep sky objects and listed in the NGC have been subsequently shown to be ordinary stars, so their inclusion in the catalog is now considered erroneous.
