# The unfolded antineutrino energy spectrum (of IBD reaction) above 7 MeV at Daya Bay. 
# The fission fractions of $^{235}$U, $^{238}$U, $^{239}$Pu, and $^{241}$Pu are 0.564, 0.076, 0.304, and 0.056 respectively.
# The spectral uncertainty and flux uncertainty of the measurement are included here. 
# The covariance matrix of the antineutrino energy spectrum of IBD reaction is also included in this file (see more below). 
# The binning method of the histogram (unit: MeV): 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11 
# The content in each bin has been divided by the bin width.
