Neutrino Oscillation Analysis of 217 Live Days of Daya Bay and 500 Live Days of RENO

We present a neutrino oscillation analysis of two particular data sets from the Daya Bay and RENO reactor neutrino experiments
aiming to study the increase in precision in the oscillation parameters sin22θ13 and the effective mass splitting Δm2
ee gained by
combining two relatively simple to reproduce analyses available in the literature. For Daya Bay, the data from 217 days between
December 2011 and July 2012 were used. For RENO, we used the data from 500 live days between August 2011 and January
2012. We reproduce reasonably well the results of the individual analyses, both rate-only and spectral, defining a suitable χ2
statistic for each case. Finally, we performed a combined spectral analysis and extract tighter constraints on the parameters, with
an improved precision between 30 and 40% with respect to the individual analyses considered.
