  Now that the NOvA experiment is approaching two years run time and has
released some preliminary data, some constraints for the oscillation parameters
can be inferred. Currently the best fits for NOvA are three separate results,
the reason they are indistinct is that they produce almost degenerate
probability curves. It has been postulated that these degeneracies can be
resolved by running antineutrinos at NOvA and/or combining its data with T2K.
However, this degeneracy resolution power can be compromised if sterile
neutrinos are present due to additional degrees of freedom that can
significantly alter the oscillation probability for any of the current best
fits. We aim to investigate this degradation in predictive power and the effect
of the DUNE experiment on it.

light of the 2018 NOvA data we also consider the same fits but with
theta_{23}=45 to see if the sensitivity results are different.
