*Table 10:* LVL2 and EF output rates for minimum bias events, LVL2 trigger efficiencies and numbers of expected <nop>BsDsA1(mu4) events without or with selection cuts. Rates set in _italics_ are estimates based on the interpolated and extrapolated rates given in Table 7. LVL2 output rates marked by <sup>&#945;</sup> are downscaled by a factor two, the estimated rate reduction for a D<sub>s</sub> vertex requirement at LVL2. For EF output rates marked by <sup>&#946;</sup>, an estimated rate reduction factor of 60 accounting for EF %bs% reconstruction is applied. (See section 3.5 for details.) The results in the columns "LVL2 eff." and N<sub>LVL2 output</sub><sup>BsDsAs</sup> (without and with selection cuts applied) are based on the <nop>BsDsAs(mu4) Monte Carlo data sample. Numbers marked by <sup>#</sup> are corrected for the estimated efficiency loss by a D<sub>s</sub> vertex requirement at LVL2. The integrated luminosities and expected event numbers correspond to one year running at the given instantaneous luminosity (10<sup>7</sup> seconds).

*Figure 6:* Wrong tag fraction as functions of tagging muons transverse momentum %pt%(&#956;) in (a) and (b) and wrong tag fractions as functions of signal Monte Carlos %bs% transverse momentum %pt%(%bs%) in (c) and (d). The wrong tag fraction is shown with mixing of the tagging side b hadron and without mixing. Without mixing, the different sources of wrong tags are shown. The main contribution is coming from b&#8594;c&#8594;&#956; followed by additional c pairs. Additional sources shown are muons coming from J/&#968;, &#966;, &#961;, &#951; and &#964;.
