Abstract
The appearance data of T2K experiment has given a glimpse of the allowed parameters in the hierarchy- parameter space. In this paper, we explore how this data affects our expectations regarding the hierarchy sensitivity of the NOA experiment. For the favourable combinations of hierarchy and , the hierarchy sensitivity of NOA is unaffected by the addition of T2K data. For the unfavourable combinations, NOA data gives degenerate solutions. Among these degenerate solutions, T2K data prefers IH and in the lower half plane over NH and in the upper half plane. Hence, addition of the T2K data to NOA creates a bias towards IH and in the lower half plane irrespective of what the true combination is.
