REFNEBULAE ivo://nasa.heasarc/refnebulae NASA/GSFC HEASARC Magakian 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source Several catalogs of reflection nebulae have been merged to create a uniform catalog of 913 objects. It contains revised coordinates, cross-identifications of nebulae and stars, as well as identifications with IRAS point sources. The HEASARC has endeavored to render all identifications of the nebulae in the various catalogs according to the styles recommended by the Dictionary of Nomenclature of Celestial Objects. This table was created by the HEASARC in October 2012 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/399/141"&gt;CDS Catalog J/A+A/399/141&lt;/a&gt; file table1.dat.
