Jobs

Priority	Task	Person	Method
1	Cluster Finding	Jon Paley	Pick up diagonally connected hits in clustering, and take into accout dead pads.
	Track Finding		Allow tracks to share hits. Look not just along z-dir. but towards target/vertex in order to find high p_t tracks.
1	T0 Shift + Drift Velocity	Jon Paley	(1) Use BC beam fit + TPC Reco tracks that exit top of TPC. (2) Use TPC Tracks + DC Wire Hits.
1	Gain	David Miller Mike Heffner	Plot ADC/fit_frac for pads in beam, show magnitude of variation along x,z
1	Hit finding	David/Jenn/Mike	Fit to Gauss in x, Gamma in y, show sample fits
1	Distortion	Ron Soltz	Implement Rolandi-Blum distortion, plot corrected residuals for beam tracks
2	Vertexing	Jon Paley	Implement straightline-swim iterator, plot vtx x vs. y
2	dE/dx	Jenn Klay	Plot unoptimized dE/dx vs. 1/R, then optimize truncation
2	Track Fitting	Jon Paley
2	Geometry	Peter Barnes
	Alignment
3	Particle ID	Jenn Klay
3	Secondary Vertices (V0)	Jon Paley Mike Heffner
3	Monte Carlo: Gain Distortions
