$^{c}$ The IBAS \textit{Detector Programs} were in idle mode owing to the limited telemetry
allocation for IBIS/ISGRI during this observation. See Ref.~2 for details.\\
$^{d}$ The localization of this  GRB was complicated by the fact that it was
detected while  the satellite was performing a slew between two pointings.
This also reduced its significance level below the threshold for immediate alert distribution.
See Fig.~\ref{fig5} for the resulting error regions.
