Abstract: This data set includes the raw column densities of several gas species observed in the spectra of comet Borrelly, as a function of position in the coma. All measurements were made with the 2.7-m Harlan J Smith Telescope at McDonald Observatory. During the 1981 and 1987-1988 apparitions, the data were obtained with the Intensified Dissector Scanner (IDS), and during the 1994 apparition, the data were obtained with the Large Cassegrain Spectrograph (LCS).
