Lynds Catalog of Dark Nebulae
Listed in NASA Data Portal
This catalog is an updated version of the original version of the Lynds' Catalog of Dark Nebulae that was published in 1962.
Description
The catalog was based on a study of the red and blue prints of the National Geographic - Palomar Observatory Sky Atlas. The catalog contains positions for the centers of dark nebulae or clouds found by Lynds, values for the cloud sizes in square degrees, visual estimates of their opacity, and cross-identifications to Barnard Objects which are associated with the tabulated clouds.
This HEASARC version of the LDN Catalog was created in June 1997. It was derived from <a href="cdsarc.cds.unistra.fr/ftp/cats/VII/7A">CDS Catalog VII/7A</a> obtained from <a href="cdsarc.cds.unistra.fr/ftp/cats/VII/7A/">https://cdsarc.cds.unistra.fr/ftp/cats/VII/7A/</a>. Please refer to the CDS <a href="cdsarc.cds.unistra.fr/ftp/cats/VII/7A/ReadMe">"Historical Notes"</a> for details regarding the lineage of this version.
