DPA follow-up review, Malargüe, Nov/2000 Data Processing and Analysis DPA Task Overview FD Simulation (cont) Status for EA : Simulation of SD +FD operational Need integration with trigger, noise + electronics Resources needed: Help to integrate noise and electronics into sim. As well as trigger. Milestones: Output compatible with CDAS output (prototype at end of January). Inclusion of “realistic noise” to generate reconstructions files (january) Simulation of detailed FD, with imperfections of mirrors + cameras + integration with Geant 4 surface array (July).

8. DPA follow-up review, Malargüe, Nov/2000 Data Processing and Analysis DPA Task Overview Shower detector interface Sub-task leader: Pierre Billoir Status: Inteface exist in crude form, for connection between shower and SD+FD sim, not yet very user friendly. Status for EA: Operational. Needs some tunning. Using ROOT as intermediate steps Resources needed: Resources are sufficient for the moment Milestones: Operational interface (done) User friendly interface, isolating user from specific details (middle of the year)

9. DPA follow-up review, Malargüe, Nov/2000 Data Processing and Analysis DPA Task Overview Reconstruction  SD Reconstruction  FD reconstruction  Hybrid reconstruction Sub-task leader: Pierre Billoir with help from Bruce Dawson and Brian Fick Status:  Prototype structures working for SD, FD and Hybrid. Needs a lot of tunning (in particular from the FD part)  Simulation+Reconstruction chain: Example working from Aires to SD+FD  ROOT interfaces with simulation working, but need to be streamlined. Start from pe. counting at detectors  Mixed Fortran and C++  Need isolate structure from algorithms Status for EA: Integrated (SD+FD) will be ready by the end of January

10. DPA follow-up review, Malargüe, Nov/2000 Data Processing and Analysis DPA Task Overview Reconstruction (cont) Resources needed: Every physicist in collaboration! Milestones: Prototype of integrated SD+ FD (operating with two eyes) operational (end of January) Structure with stereo eyes (middle of the year) User friendly structure, isolating the user from nitty gritty I/O, from sequence of calling routines, focus only on physics arguments and algorithms (optimistically by the end of next year)

11. DPA follow-up review, Malargüe, Nov/2000 Data Processing and Analysis DPA Task Overview Analysis Tools  Visualization tools  Common Software library  Documentation system Sub-task leader: Luis Prado Jr. Status:  Analysis environment: LINUX (recomend RedHat/Mandrake distribution)  Visualization tools defined: ROOT, QT, OpenGL (Mesa). Some examples worked out (FDVC) seehttp://www.ifi.unicamp.br/~pradojr  Common software library no concrete work yet (needs have still to be identified)  Documentation tools being tested: Doxygen

12. DPA follow-up review, Malargüe, Nov/2000 Data Processing and Analysis DPA Task Overview Analysis Tools (cont) Status for EA: Some tools defined and prototypes implemented, but still needs lots of work to them tobecome effective. Input of needs from users are necessary. The number of tools will grow with demand. But basic structure is set. Resources needed: Computers experts with experience in Object Oriented Programing to improve the visualization tools. Milestones: Prototype of integrated visualization of SD+FD (middle of the year). ROOT analysis framework for non- experts, to do PAW-like analysis (middle of the year)
