Run 113483, 217000 events. Wedge 5 only, Chi2<30.

d'=d-0.1410*sin(phi)-0.42318cos(phi)
d''=d'+0.38e-3+0.24e-4 *z0

Plot 1: d vs phi

Plot 2: d' vs z0

Plot 3: d', Pt>2 GeV

Plot 4: d'', Pt>2 GeV. Fitted width: 91 micron. In the Commissioning Run,
same conditions (except layers used were 0124 instead of 0123) and cuts,
the width was 67 microns.
