Scientific paper

We present the catalogue of gamma-ray bursts (GRB) observed with the WATCH all-sky monitor on board the GRANAT satellite during the period December 1989 to September 1994. The cosmic origin of 95 bursts comprising the catalogue is confirmed either by their localisation with WATCH or by their detection with other GRB experiments. For each burst its time history and information on its intensity in the two energy ranges 8-20keV and 20-60keV are presented. Most events show hardening of the energy spectrum near the burst peak. In part of the bursts an X-ray precursor or a tail is seen at 8-20keV. We have determined the celestial positions of the sources of 47 bursts. Their localisation regions (at 3-sigma confidence level) are equivalent in area to circles with radii ranging from 0.2 to 1.6deg. The burst sources appear isotropically distributed on the sky on large angular scales. (1 data file).
