\begin{table}
\caption{\label{table1}GRBs localized and/or observed by BeppoSAX.
We indicate the position of the first TOO start and end times, the sum
of the Good Time Interval (GTI), and the date of the subsequent
TOOs. "WFC'' following the position means that this GRB~was
localized only the the WFC, "NFI'' a localization obtained by NFI. An
external trigger of a BeppoSAX TOO is indicated by giving the satellite that localized the burst in parenthesis, but the
localization displayed has been provided by NFI. We also indicate in
the table if an optical afterglow was detected together with the
distance and other information obtained from the
optical study.}
