 Upper panel: The acceptance of kaons decaying in the fiducial volume of the TPC as a function of thekaon $\pt$ for $\rm{K}^+$ (full-triangles) and $\rm{K}^-$(open-squares). Lower panel: The efficiency of reconstructed kaons from kinks as a function of the $\pt$ (mother), separately for $\rm{K}^+$ (full-triangles) and $\rm{K}^-$ (open-squares). The contamination from wrongly associated kinks is also plotted for both charges (lower set of points).
