1  The leptons are required to have $\mathit E_{{{\mathit \ell}}}>1.5$ GeV/$\mathit c$.
2  Uses minimum lepton energy of 1.5 GeV and also reports moments with $\mathit E_{{{\mathit \ell}}}$ $>$ 1.0 GeV.
3  Moments are measured with a minimum lepton momentum of 0.7 GeV/c in the ${{\mathit B}}$ rest frame;
