A second catalogue of equivalent widths of the interstellar 2200 Å band is presented. It is based on spectrophotometric data obtained with the TD‐1 satellite and supplements a catalogue already published (paper I). Both catalogues list a total of 779 stars. The reliability of the derived parameters is analysed. There is a satisfying agreement with spectrophotometric data obtained with the OAO‐2 satellite. The relationship between the equivalent width of the 2200‐Å band and and the colour excess is discussed, making use of additional data for more strongly reddened stars obtained with OAO‐2 and IUE.
