Summary and conclusions
Actively involved in the system set-up, particularly in DAQ;
ON-LINE analisys at a rate of & 5 kHz/crys, with two ATCs;
AGAVA coupling;
Simulation tool for RDDS measurement (EPJA09 in press,PRC under submission).
TO DO/ ON GOING
Presort and sort of data: improv. of the algorithms and sortcode.
last (two?) commissioning test + physics campaign(displacement of the ATC3);
Simulations in view of the next LNL PAC and to reproducecommissioning results.

LibrariesWhat are they really?
C/C++ code
The BASE CLASS usually binds with the ADF:I/O methods, configuration, initialization
The DERIVED CLASS usually overloads the processingmethod where the job is done
(symbols for Narval interface)
ORGANIZATION INSIDE NARVAL
All the C/C++ code is in a dedicated machine where all thelibraries have been ported and build. Afterwards they arecopied to a common nfs directory, loaded and configured insideNARVAL.
