  We consider direct bounds on the coefficients of higher dimensional top quark
dipole operators from their contributions to anomalous top couplings that
affect some related processes at the LHC. Several observables are studied. In
particular, we incorporate for the first time in this type of analysis the
recently measured associated $t \bar{t} V$ production, which is currently the
only measured direct observable sensitive to the dipole operator involving the
hypercharge field. We perform a Bayesian analysis to derive the $1(2)\sigma$
confidence level (CL) intervals on these coefficients.
