How to look at histograms :

• source ~cdfsoft/cdf2.cshrc
• setup cdfsoft2 (this also sets up root)
• start root: root
• new TBrowser(); (TBrowser window pops-up)
• open  your directory Folder (double clik on icon)
• go to File and Open...
• select SVTMon_#####.root and click Open
• open folder ROOT Files
• double clik on the file icon,  you get  all the histogram icons
• finally, double click on the histogram icon you want, a canvas window pops up.
• ..... to quit root: .q

List of histograms:
(sample plots are from run 128446 - oct 6 2001- taken with the requirements: at least 2 SVT tracks, with chi2<25, abs(d)>50micron and Pt>2GeV)

Filled for each event

• Number of SVT tracks / event
• Event status flags set to 1 (bits 9:16 from EE word)
• Number of words in SVTD bank
• EEwords found

• Chi2 (all Tracks)
• Chi2 (barrel by barrel)
• Impact parameter (cm)
• Phi0 (rad) barrel by barrel
• Impact parameter vs Phi0 (all tracks)
• Impact parameter vs Phi0 (barrel by barrel)
• unsigned Pt (GeV/c)
• Curvature (cm-1)
• Wedge occupancy (barrel by barrel)
• Pattern occupancy
• semibarrel occupancy (z_in)
• semibarrel occupancy (z_out)
• Hits coord. with respect to wedge border (cm)
• Fit Quality (bits 0:3 from TF status word)
• TF error flags set to 1 (bits 5:11 from EE word)
• for the linked XFT track:
• XFT linker number (barrel by barrel)
• unsigned Pt (GeV/c)
• Phi0 (rad)
• Phi0_XFT - Phi0_SVT
• Curv_XFT - Curv_SVT
