Input ic3 test file Simulation : Sirene G4 Question : output ic3 test file A module of km3tray contains Sirene, A module of km3tray contains GEANT4 (Claudio) Comparison ? Smith and Baker water absorption still to be simulated : we will keep NEMO water as reference Communication : Each code (gen, sim, rec) has to read/write ascii files (tags; format already defined and easily usable) ?? : final conclusion : when data files are provided, they have to be associated to a clear documentation in order to be decoded by the receiver. Repository for documentation Detector files : will be as simple as possible for exchange between software frameworks : (PMT_NUMBER) x y z vx vy vz : coordinates of the photocathode center and of the vector indicating the orientation of the photocathode. Reconstruction : Work has to be continued to use different reconstructions and filtering. Criterions to compare reconstructions : effective area has to be given with the corresponding sensitivity and atm muon contamination. Optimization : Fast tools useful to rapidly test simple variations. Other tools to test more deeply the main possibilities, with muons Energy estimator : in a first instance, possibility to use a degraded MCTruth ? : to avoid Optimization/comparison criterian : Point source sensitivity plot vs declination for a given cost.

Depth effect not so big for point sources ? “Not intuitive” results In case of tower: bar length no so important ? PMT orientation not so important ? Work to do Better understanding of reconstruction effect & cuts : different, depending on the study. Point sources have to be the main guideline. Diffuse fluxes (and showers) are not a first priority Energy estimator has to be developed now. Distance between lines : important, but strongly constrained by deployment : 2 reference layout : 1 for each design (lines, towers) Fix the level of relevancy of WP2 outputs, Cost Model
