We describe Interplanetary Network (IPN) detection and localization information for 554 gamma-ray bursts (GRBs) observed as triggered and untriggered events by BATSE.

This annulus generally intersects the BATSE error circle, resulting in a reduction of the area of up to a factor of ˜ 650.

Abstract

We describe Interplanetary Network (IPN) detection and localization information for 554 gamma-ray bursts (GRBs) observed as triggered and untriggered events by BATSE. For any given burst observed by BATSE and one other distant spacecraft, arrival time analysis (or “triangulation”) results in an annulus of possible arrival directions whose half-width varies between 14 arcseconds and 5.6 degrees, depending on the intensity, time history, and arrival direction of the burst, as well as the distance between the spacecraft. This annulus generally intersects the BATSE error circle, resulting in a reduction of the area of up to a factor of ˜ 650. When three widely separated spacecraft observed a burst, the result is an error box whose area is as much as 30000 times smaller than that of the BATSE error circle.
