Welcome to the DIB Database
This site contains information from the Apache Point Observatory Diffuse Interstellar Band (DIB) collaboration. It currently consists of links to our publications and an archive of our published data products, and it will ultimately contain links to published versions of the complete DIB Database compiled by this collaboration.
Here are links to our published papers, and associated data products:
