The catalog contains a homogeneous set of optical spectrophotometric observations (3300-7300 angstroms) at moderate resolution (about 10 angstroms) of 86 Wolf-Rayet carbon and oxygen stars in this galaxy, the Large Magellanic Cloud, and the Small Magellanic Cloud. The observations were made with the Intensified Reticon Scanner on the white spectrograph of the 0.9 m telescope at Kitt Peak and with the SIT-Vidicon detector on the Cassegrain spectrograph of the 1.5-m telescope at Cerro Tololo Inter-American Observatory.
