Detailed Description

Main program to simulate detector response to muons and showers.

Picture by Claudine Colnard

Note that CDF file descriptor should contain the wild card character JPHYSICS::WILD_CARD;
The file names are obtained by replacing JPHYSICS::WILD_CARD; with

• JPHYSICS::DIRECT_LIGHT_FROM_MUON;
• JPHYSICS::SCATTERED_LIGHT_FROM_MUON;
• JPHYSICS::DIRECT_LIGHT_FROM_DELTARAYS;
• JPHYSICS::SCATTERED_LIGHT_FROM_DELTARAYS;
• JPHYSICS::DIRECT_LIGHT_FROM_EMSHOWER; and
• JPHYSICS::SCATTERED_LIGHT_FROM_EMSHOWER, respectively.

The CDF tables can be produced with the script JMakePDF.sh:

JMakePDF.sh -P

(option -h will print all available options). Note that the script will launch a large number of processes (JMakePDF and JMakePDG)
which may take a considerable amount of time to completion.
On a standard desktop, all jobs should be finished within 1/2 a day or so.

The same script should then be run with option -M to merge the PDF files, i.e:

JMakePDF.sh -M

CDF tables are obtained by running the same script with option -C, i.e:

JMakePDF.sh -C

The various PDFs can be drawn using the JDrawPDF or JDrawPDG applications.
The tabulated PDFs can be plotted using the JPlotPDF or JPlotPDG applications.
The tabulated CDFs can be plotted using the JPlotCDF or JPlotCDG applications.
