Query: Parameter degeneracies and new plots in neutrino oscillations   It is shown that plots of constant probabilities in the $(\sin^22\theta_{13},
1/s^2_{23})$ plane enable us to see eightfold degeneracy easily. Using this
plot, I discuss how an additional long baseline measurement resolves
degeneracies after the JPARC experiment measures the oscillation probabilities
$P(\nu_\mu\to\nu_e)$ and $P(\bar{\nu}_\mu\to\bar{\nu}_e)$ at $|\Delta
m^2_{31}|L/4E=\pi/2$.
