This directory contains Cartes du Ciel nebula databases that plot the boundaries of charts 1 to 50 (omitting 27) E.E. Barnard's A Photographic Atlas of Selected Regions of the Milky Way (1927) (two volumes).  

Many of the chart's perimeters overlap. For visual clarify, the databases are split into three parts: 

Database "bcd1.dat" - constellation and (plate nos): 

	Aql-Sct (34-41) Group 
	Cyg-Cep (43-50) Group
	Per-Cas (1-2) Group 
	Per-Aur-Ori (3-9) Group 
	CMa (10) Group

Database "bcd2.dat" - constellation and (plate nos): 

	East Sgr (28-31) and East Sco (19-22)

Database "bcd3.dat" - constellation and (plate nos): 
 
	West Sgr (23-26) and West Sco (11-18) Groups 

These plots are intended to be principally used visually in orienting Mary R. Calvert's charts in Vol 2 of the Atlas to the night sky.   

The Atlas is distributed at no charge over the internet by the Georgia Institute of Technology. << http://www.library.gatech.edu/about_us/digital/barnard/index.html accessed 8/4/2005 >>. 

A supplemental database that plots the positions of the Barnard dark cloud objects is available at the Cartes du Ciel website.
