We have reanalysed the atmospheric neutrino data including new results from
Super-Kamiokande and Soudan-II experiments, under the assumption of two-flavor
neutrino oscillation. We present the allowed region of oscillation parameters
for the νμ​→ντ​ channel. In performing this re-analysis we also
take into account some recent theoretical improvements in the flux
calculations.Comment: Latex file, 2 pages including 2 ps figures, Talk presented by H.
