The Interstellar 2200 Å Band: A Catalogue of Equivalent Widths (Mitteilungen der Universitäts-Sternwarte zu Jena Nr. 151)

Using the data of the Ultraviolet Bright-Star Spectrophotometric Catalogue, the equivalent width of the interstellar absorption band at 2200 Å is derived for 422 stars. A preliminary statistical analysis confirms the good correlation between the equivalent width of the 2200 Å band and the colour excess. The wavelength position of the band centre seems to vary to a small extent.
