== Event display ==

The event display has two projections: x-y and y-z.
All detector subsystems are presented.
Some of them overlay, especially PIDs, it is not important for parametric simulation, but let's study several options at once.
All particles from AllGenParticles branch are presented at the plot by lines of different styles, colours and thicknesses.
Somehow the line thickness corresponds to the particle mass, the wide line --- the more massive particle.
Warm colours are devoted to positive charged particles and cold to negative ones.
Also, particle lines are labeled.

The event display is switched on by default. To switch it off run simulation with <code>-b</code> option.

== Detector configuration ==

The detector parameters can be changed via a configuration file ''my_cfg_file.dat'' placed in the main simulation folder.
The file has a simple structure --- one parameter and its value(s) per line.
A parameter's name and value should be separated by spaces.
Arrays should be written in [] brackets.
The values in arrays should be separated by commas.
Empty lines and lines contained incorrectly parameter names are ignored.

In the example below the parameter at the first line and the second line is one number,
while the parameter at the third line is an array.

trck.minPt 0.05
trck.corrMtx.pij -0.08
calo.resPar [0.167,0.0,0.011]
</pre>

The parameters can be given in any order.

All detector parameters can be viewed in the configuration files:

|-
! Subsystem
! Congiguration file
! Name to change parameters
|-
| ASHIPH
| <code>ashiphpars_std01.json</code>
| <code>ashiph1030</code>

| Calorimeter

|-
| ToP
| <code>toppars_std01.json</code>
| <code>top</code>
|-
| Tracker
| <code>trkpars_std01.json</code>
| <code>tracker</code>
|}

The detector subsystems sizes are stored in <code>detlayout_std01.json</code>. They can be changed in the same way.
