This is the data of the paper arXiv:1112.1979:

Gamma-ray Activity in the Crab Nebula:
The Exceptional Flare of April 2011

Units and variables are indicated at the top of each file.
The data filenames indicate the figure in which the data is shown.
For the spectra in fig 6 the name also indicates the time range 
in MET (Mission Ellapsed Time = seconds since UTC 2001-1-1 0:0:0).
Flux values and upper limits are given for each points. Also given
is the TS value. For a TS<4 upper limits were shown in the paper,
as flux points are not trustable under this condition. The used
tempo2 pulsar ephemeris file is named crab_ephemeris.par.
