  Recent measurements like the t tbar gamma production by CDF as well as the
Br(B ->Xs gamma) and ACP (B->Xs gamma) are used to constrain the magnetic and
electric dipole moments of the top quark. The B->Xs gamma measurements by
themselves define an allowed parameter region that sets up stringent
constraints on both dipole moments. Actually, significantly more stringent than
previously reported. The measurement by CDF has a 37% error that is too large
to set any competitive bounds, for which a much lower 5% error would be
required at least. On the other hand, because of the LHC's higher energy (apart
from its higher luminosity) the same measurement performed there could indeed
further constrain the allowed parameter region given by the B->Xs gamma
measurement.
