In order to find a time correlation between the two different phenomena we
have chosen as reference time () the GRB trigger time.
Then we searched how many EXPLORER events occured in a time window of
s around the
. In this way we found 4 GRBs, over the 557
analysed, that have a GW event in this time window.
The Table 1 reports the occurrence date and the peak
flux counts in photons cm-2 s-1 of the GRBs. As the EXPLORER detector
has dependent GW cross section, where
is the angle
between the direction of the source and the principle axis of the antenna,
we also report this value in the table.
These coincidence events are then analysed to search particular deviations
from the
BATSE distribution and from the
distribution of all 557 GRBs, because we
would expect an excess of events in coincidence with GRBs
located closer to us and in better direction respect to
the antenna.
The Kolmogorov-Smirnov test between the two distribution
with the and the peak flux of these 4 bursts, and those
obtained with the all 557 GRBs, gives respectively a value of 75%
and 53% that they are compatible.
