Re: Tracking tasks

[David Lawrence <davidl@jlab.org>]

Hi Elton,

    In addition to these items, I feel it is important to do the 
wire-based track fitting exercise discussed earlier. That should give us 
a lot more confidence that the overall procedure and general fitting 
algorithm are sound.

Regards,
