26. Summary First generation analysis published Second generation analyses mature: – IC79: Being reoptimized Better bgr estimate, from data – IC86: First year completed Better energy reco before adding data Multiyear analysis Third generation analyses: – Better tools (MultiLlh, energy reconstruction,…) – Better simulations – Higher statistics, multiyear data sets – Search for tau appearance
