The Ulysses supplement to the BATSE 3B catalog of cosmic gamma-ray bursts

We present interplanetary network localization information for 218 gamma-ra y bursts in the third BATSE catalog obtained by analyzing the arrival times of these bursts with the Ulysses and Compton Gamma Ray Observatory spacecr aft. For any given burst observed by these two spacecraft, arrival time ana lysis (or "triangulation") results in an annulus of possible arrival direct ions whose half-width varies between 7 " and 32', depending on the intensit y and time history of the burst and the distance of the Ulysses spacecraft from Earth. This annulus generally intersects the BATSE error circle, which results in an average reduction of a factor of 30 of the error box area.
