    • There have been several attempts to reconcile all detected anomalies with a scheme involving only three neutrino flavors, suggesting for example that (Formula presented) 67, or that (Formula presented) 8. The first scenario predicts the absence of a zenith angle dependence of the atmospheric neutrino anomaly, the second one predicts a constant suppression for all solar neutrino experiments and, since the atmospheric neutrino anomaly is essentially due to (Formula presented) in this case, a positive signal for the CHOOZ experiment 9; therefore both scenarios are currently not supported by the data

    • We note that in 17 the authors have considered only the case of positive (Formula presented) Matter effects allow to distinguish the case of positive and negative squared mass differences, and the allowed region for (Formula presented) is somewhat larger than in the other case, because of the MSW resonance present for the neutrinos
