Inclusive Rapidity plots

This set of plots shows the invariant cross section on the rapidity - transverse velocity plane for various producs. Target, center-of-mass and beam rapidity is marked by arrows. Note, that the absolute value of the mass was used to bin the data. The file names look like

     dst_0_v_ref_z01a1b9_00.ps.gz    from single reference run
   10dst_0_v_ref_z01a1b9_00.ps.gz    from 10 DST files
                 ^  ^    ^
                 |  |    page number
                 |  mass of product
                charge of product

Note, that all plots are for the total trigger cross section as indicated by the `b9' in all file names.

Centrality selected Rapidity plots

As above, but here one page shows 9 rapidity plots for one system for different centrality cuts. Bin=1 is most peripheral and Bin=8 most central, while Bin=9 is again the inclusive case.

Ring-by-Ring Z vs E/A plots

This set shows `ring-by-ring' the z vs E/A distribution. Each page shows 4 columns

• z vs E/A for full z range. Projectile charge and velocity marked by lines.
• the full z distribution
• z vs E/A for z up to charge 12. The beam velocity and charge 10 are marked by lines
• the z distribution up to 12, charge 10 is marked by a line

The file names look like

     dst_0_ze_ref_r01b9_04.ps.gz    from single reference run
   10dst_0_ze_ref_r01b9_04.ps.gz    from 10 DST files
                  ^     ^
                  |     page number
                  ring number (r00 means all rings)

Note, that all plots are for the total trigger cross section as indicated by the `b9' in all file names.

Ring-Module hit rate plots

This set shows the distribution of hits for various products as a function of a ring-module coordinate. The file names look like

   10dst_0_rm_ref_01.ps.gz
                   ^
                   page number - one page per system

A quite simple `good hit' selection was used based on

    identification code = 1 - 3    (CsI, Si or Chio pid)
    calibration code    = 2 - 4    (accept warnings, discard errors)
