  2. Pending Issues • Physics Priority • < 1 TeV: Dark matter • 1-100 TeV: HESS sources, GRBs • >1 PeV: Diffuse flux, GZK, AGN • Evaluation of NEMO geometry • Evaluate effect of energy measurement on sensitivity • Rejection of downgoing atmospheric muons • Cost Model • Reconstruction of electron and tau neutrinos • energy resolution, direction resolution • Specification of front end? • Time resolution, dynamic range, 2 track separation, • 1 vs 2 photon separation, dead time….

  3. More Issues • Standard simulation/analysis framework • ANTARES/NEMO soft (KM3, geasim….) • NESSY-mathematica • SIRENE/MMC+PHOTONICS • KM3TRAY • KM3NET internal notes • For us • For reference in CDR • CDR writing framework • Word, latex, something else? • Extrapolation of Auger observations • Manpower
