      This database table contains the Reference Catalog of Galactic Novae, Duerbeck, version 1990. It lists all objects known or believed to be novae at one time or other. Objects that were later found to be spurious have been omitted. Completeness was attempted only for novae and not for dwarf novae, X-ray novae, etc. This is a service provided by NASA HEASARC .
