L1 Rate Reduction by Adding RPCs to BIS: The picture shows the difference between the Eta coordinate of mboy segments inside the BIS7 chamber and the Eta coordinate of L1MU20 ROIs associated to reconstructed muons with transverse momentum greater than 20 GeV, calculated using data from the physics muon stream. The DeltaEta calculated using ROIs associated to positive muons is drawn in red, while the one calculated using ROIs associated to negative muons is drawn in blue. Almost all the signal is concentrated in the region |DeltaEta|<0.04 |

L1 Rate Reduction by Adding RPCs to BIS: The picture shows in black the difference between the Eta coordinate of mboy segments reconstrucet in BIS7 chamber and the Eta coordinate of L1MU20 ROIs, using data from a 25 ns enhanced bias stream. The DeltaEta calculated using ROIs associated to positive muons is drawn in red, while the one calculated using ROIs associated to negative muons is drawn in blue. Applying a cut of |DeltaEta|<0.04 it is possible to reject about 40% of background, especially low pT muons. |

L1 Rate Reduction by Adding RPCs to BIS: The picture shows the geometrical coverage in range 1< Eta <1.3, obtained drawing the Eta-Phi coordinates of reconstructed muons from the physics muon stream, associated with EndCap trigger and segments inside the EI, BIS6, BIS7, BIS8 chambers |

L1 Rate Reduction by Adding RPCs to BIS: The picture shows how the distribution of the transverse momentum of the reconstructed muons changes applying a different cut in DeltaEta between the segments inside the chambers and the L1_MU20 ROIs. The distribution obtained with DeltaEta < 0.2 is drawn in blue, while the one obtained with DeltaEta < 0.04. As can be seen, a thight cut in Dh permits to reject muons with transverse momentum smaller than 20 GeV, which is the nominal pT lower limit of the trigger. |

L1 Rate Reduction by Adding RPCs to BIS: The picture shows the L1_MU20 Efficiency with respect to all reconstructed muons as a function of the muon momentum, for two different cuts in DeltaEta between the segments inside the chambers and the L1_MU20 ROIs. The curve obtained with DeltaEta < 0.2 is drawn in blue, while the one obtained with DeltaEta < 0.04 is drawn in red. |

L1 Rate Reduction by Adding RPCs to BIS: The picture shows the Eta distribution of the reconstructed muons from the physics muon data stream. The hatched distribution is the one obtained with the actual trigger, while the full colored one shows how the distribution in EndCaps changes applying the request of RPCs in BIS6, BIS7 and BIS8. In transition region (1.05< |Eta| <1.24) the fraction with hits on EI or BIS chambers is 80.1%. |
