Description
Currently, csspec applies a 20% margin to determine the true energy range from the reconstructed energy range. This appears not to be sufficient for HESS data. A solution would be to check the RMF and get the corresponding energy boundaries, but even simpler, all etrue energy bins could be used.
Recurrence
No recurrence.

csspec now uses the full true energy range of the RMF for an On/Off analysis, making sure that the tails of the energy dispersion are not cut in case that they are wider than the 20% margin.
Specifically, the following code is now implemented in csspec._select_onoff_obs():
# Select energy bins in etrue and ereco. All etrue energy bins are
# selected. A 0.1% margin is added for reconstructed energies to
# accomodate for rounding errors.
etrue = obs.rmf().etrue()
ereco = gammalib.GEbounds()
itrue = [i for i in range(obs.rmf().etrue().size())]
ireco = []
for i in range(obs.rmf().emeasured().size()):
ereco_bin_min = obs.rmf().emeasured().emin(i)
ereco_bin_max = obs.rmf().emeasured().emax(i)
if ereco_bin_min * 1.001 >= emin and ereco_bin_max * 0.999 <= emax:
ereco.append(ereco_bin_min, ereco_bin_max)
ireco.append(i)
