The systematic uncertainty on the lepton acceptance consists |

of two parts: the trigger efficiency uncertainty and the |

The trigger efficiency |

for two leptons of $P_T>10$ GeV, with one lepton of |
| 24 |

$P_T>20$ GeV is very high, except in some corners |

We estimate the efficiency uncertainty to be a few percent, |

mostly in the low $P_T$ region. |
