r6164 r6222 5 5 \par 6 6 7 The Burst Alarm System is installed and working since last summer 8 in La Palma. The duty of the Burst Alarm System 9 is to perform a full-time survey of the {\it GRB Coordinates Network} (\g)~\cite{GCN} alerts. Different satellite experiments perform GRB monitoring 10 in their wide FOV and send immediately the coordinates of the GRBs to the \g network. 11 The network send the alerts to registered users and allows other satellites as well as 12 ground based observatories to observe the GRBs and their afterglows at different wavelengths. 13 The Burst Alarm System is composed by a core program - 14 which acts in two ways: on the 15 one hand it manages the monitoring of the \g, on the other it manages 16 the communication with the Central Control (CC). Then it also manages 17 three communication channels to notice the shifters 18 about an alert situation. The program is called {\it gspot} (Gamma 19 Sources Pointing Trigger). It is a C based daemon running 24 7 The Burst Alarm System {\it gspot} (Gamma 8 Sources Pointing Trigger) is working in La Palma since last summer. 9 It performs a full-time survey of the {\it GRB Coordinates Network} (\g) alerts~\cite{GCN}. 10 Different satellite experiments 11 send GRB coordinates to the \g which distributes 12 the alerts to registered users. 13 The Burst Alarm System is composed of a core program which 14 manages the monitoring of the \g and the communication with the Central Control (CC). 15 It also handles three communication channels to notice the shifters 16 about an alert. It is a C based daemon running 24 20 17 hours a day on the {\it www} machine, our external server, in a 21 18 {\it stand alone} mode. It does not need to be operated and is … … 24 21 25 22 26 \subsection{The connection to GCN}23 \subsection{The connection to the GCN} 27 24 28 The connection to \g is performed by {\it gspot} through a25 The connection to the \g is performed by {\it gspot} through a 29 26 TCP/IP connection to a computer at the Goddard Space Flight Center (GSFC). 30 This computer distributes the information it receives from the satellite31 experiments through the normal internet socket connection. The {\it gspot} on our32 sideacts as a server while the client, running at the GSFC,27 This computer distributes the alerts from the satellite 28 experiments through an internet socket connection. {\it gspot} 29 acts as a server while the client, running at the GSFC, 33 30 manages the communication of the data concerning the GRBs 34 31 and concerning the status of the connection. \\ 35 32 36 33 The format of the data distributed through the \g differ between the individual satellites 37 and the kind of package. There are three satellites participatingin the GRB survey:38 HETE-2~\cite{HETE}, INTEGRAL~\cite{INTEGRAL} and SWIFT~\cite{SWIFT}. All are sending alerts which include the39 UTC,coordinates (not always), error on coordinates34 and the kind of package. Currently, three satellites participate in the GRB survey: 35 HETE-2~\cite{HETE}, INTEGRAL~\cite{INTEGRAL} and SWIFT~\cite{SWIFT}. 36 The alerts include the UTC, the GRB coordinates (not always), error on coordinates 40 37 (not always) and intensity (photon counts) of the burst. 41 38 The first notices from HETE-2 and INTEGRAL usually do not include the coordinates. 42 In few cases only coordinates are distributed in morerefined notices.39 In few cases only coordinates are distributed in refined notices. 43 40 The \sw alerts are predicted to arrive with coordinates between 30-80 sec after the onset of the burst. 44 41 The error on the coordinates from the BAT detector will be 4 arcmin which is smaller than the size of one … … 196 193 197 194 \end{itemize} 195 196 %%% Local Variables: 197 %%% mode: latex 198 %%% TeX-master: "GRB_proposal_2005" 199 %%% End:
