|Subsystem||Task||Description||Category||Contact(s)||Start Date||End date||Recurrence||Responsible||FTE Accumulated|
|DC||Track Reconstruction Software||Write programs to identify clusters of hit wires, to identify possible track segments within the clusters, and to link the segments from various superlayers to form the hit ensemble used for track-fitting; also develop codes to produce trajectories through magnetic field regions and to calculate intersections with wire planes and to calculate distances of closest approach to wires. Form methods to estimate the chi-squared of such tracks and to adjust the track parameters to search for the minimum chi-squared track.||Software||Mac Mestayer||December 31, 1969||December 31, 2013||Start in 2012 or 2013; 4 - 8 hrs/wk. for one year||none||0.200|
