Description:
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.
