To the first order no, the map I am reading is correct for all energies,but I think
the delta on the energies becomes a little bit narrower
as the energy increase but this is a second order effect
that should not effect the analysis at this point.
Dan Sober generated this file and is the expert.

this is true,
We will also need this information for normalisation purpose,
what we could do right now is to use the TAGI BOS bank,
(intermediate bank)
that countains more information, T_id, E_id,
TAGI does not countain the reconstructed energy, but I can add it there very
easily.
the time in the TAGR BOS bank is actually the sum
of TimeMEAN and TRF in the TAGI bank so this is also easy to retrieve from TAGI.
and we could submit the idea to the Tagger/photon group,
of adding T_id and E_id in the TAGR Bank,
(an alternative would be to have both TAGI and TAGR generated
in the cooked files)
