Correlations of the band at 2175 Å with other interstellar features.
Abstract
Using published spectrophotometric and filter-photometric data from the OAO-2 and TD-1A satellites, equivalent widths of the ultraviolet 2175-A band are determined for 194 stars. This list of data is used to study correlations between the 2175-A band and the diffuse 4430-A, 5780-A, and 5797-A bands as well as the hydrogen column density and the equivalent width of the sodium D2 line.
