"\n StdHep Phase Display is a tool to select, display, and browse StdHep \
41
events, in order to understand the kinematics, topology and the decay chain.\
42
Such Events can easily be created based on the StdHep framework, which \
43
interfaces to most HEP generators, such JETSET, ISAJET, HERWIG \n\n\
44
After invoking Phase Display , you'll want to do one of two \
46
(--> Use scroll bar at right to see rest of this message.)\n\n\
47
Open an Native StdHep file\n\
48
Open a FZ (XL format) StdHep file\n\n\
49
Use the File pull-down menu to perform any of these functions. \n\n\
50
After specifying the file you which to browse, you need to specify \
51
the event to view. You can use the arrow buttons on the top of this \
52
panel to select the event you whish to see. Currently, you can only \
53
browse through 100 events of this file (or less). Since StdHep files are \
54
sequential, reaching further downstream would probably be too slow. \
55
At the outset, the first event in the file is shown. \
56
By default, the length of the track is mapped to the norm of the 3-mom. \
57
vector of the particle. You can change that on the panel. \
58
The color is mapped to the particle identification. The Color Code is \
59
available in the Event pull down menu\n\n\
60
The next step is to relate the kinematics to the decay chain. Under the \
61
Event pull down menu, selected the Event Tree option. More help on \

can be mapped to the momentum, transverse momentum, rapidity or \

pseudorapidity. At the beginning, it is mapped to the momentum, you \
72
can changed that by depressing (left mouse button) one of the radio buttons \

a standard tree structure is used, e.g., a particle \n\

This option display such a tree, where a node\n\

algorithm to simplify a tree, for instance, collapse \n\

Known deficiency : The Tree widget ( or Motif) has a\n\
434
bug in the DestroyWidget method, which can (and usually\n\
435
will) induce a crash of this application upon removal \n\
436
of the a Tree Display if the number of node exceeds a \n\
437
few hundreds. This bug is currently under study. \n\
438
In any event, exploring a ~500-node tree can be time \n\
439
consuming and not very useful, one can suggest various\n\
440
algorithm to simplify a tree, for instance, collapse \n\
441
all particles to the top, if they do not have an\n\
442
interesting ancestry ( e.g., they don't come from \n\
443
a top or bottom quark. \n\n\

Show Detector Sketch:\n\
445
A cartoon detector can be drawn on this display, to \n\
446
merely indicate the scale and related track directions \n\
447
and geometrical acceptances. You'll have to create a \n\
448
simple ASCII file, each line containing the \n\
449
coordinates of a line segment : \n\
450
(x1, y1, z1, x2, y2, z2), expressed in cm.\n\
451
Comments line are allowed. Free format ( %f) is used\n\
452
An example file sketch1.det is available with the \n\
453
product. Once you activate this option, you will be\n\
454
prompted to open such a file, and the display will be\n\
455
refreshed with these additional line segments,\n\

If Greek fonts are available on yourplatform ( usualy refered as a symbol \
