Query: Effect of non-zero theta(13) on the measurement of theta(23)   The moderately large measured value of theta13 signals a departure from the
approximate two-flavour oscillation framework. As a consequence, the relation
between the value of theta23 in nature, and the mixing angle measured in muon
neutrino disappearance experiments is non-trivial. In this paper, we calculate
this relation analytically. We also derive the correct conversion between
degenerate values of theta23 in the two octants. Through simulations of a muon
neutrino disappearance experiment, we show that there are observable
consequences of not using the correct relation in calculating oscillation
probabilities. These include a wrong best-fit value for theta23, and spurious
sensitivity to the octant of theta23.
