Listed in IVOA Registry (Virtual Observatory)
This catalog is an updated version from the published version.
Description
The catalog was based on the red and blue prints of the National Geographic - Palomar Observatory Sky Atlas. The catalog contains positions, both equatorial and galactic for the centers of dark nebulae.
Values for the cloud sizes are given in square degrees, and estimates of their opacity are given. The updated catalog is ordered by galactic longitude and includes cross references to the published catalog and Barnard Object numbers associated with the clouds.
