Attatched are three postscript files-

1) deltas.ps shows two sets of plots- fits using only wire centers
   are on the left and fits using "ideal" drift information are on the right.
   For each set, there are 3 histograms (6 total) for
   the "reconstructed" minus the "montecarlo" values of the
   helix radius, theta (measured from B) and momentum. The "ideal" drift
   information does not use STRs, but looks up the drift distances from
   the geant hit space points bank.

2) residuals.ps shows the residuals for the "ideal" drifts fits.

3) driftcircles.ps shows an anomaly in the drift circles, to be discussed
   at the meeting.
