Progress of track
finding in multi-track Monte Carlo data are presented. An alternative
track-seed based approach is used to identify track candidates in 2D which are then used to find tracks in 3D. Efficiencies for 4 muon track events
($\mu^+{}\mu^+{}\mu^-{}\mu^-{}$) are given as functions of kinematic
variables, $p, \phi, \theta$ and the number of hits per track.
Results are given for clean MC data as well as for ``smeared''
data with random noise hits. Results of a simulation targeting a
suggestion by the 2004 Detector Review regarding FDC package placement
are also given. Finally, the organization of the tracking code and
its implementation in the DANA framework are given.
This note documents a work in progress.
