134  *
135  * Note that CDF file descriptor should contain the wild card character JPHYSICS::WILD_CARD;\n
136  * The file names are obtained by replacing JPHYSICS::WILD_CARD; with
137  * - JPHYSICS::DIRECT_LIGHT_FROM_MUON;
138  * - JPHYSICS::SCATTERED_LIGHT_FROM_MUON;
139  * - JPHYSICS::DIRECT_LIGHT_FROM_DELTARAYS;

141  * - JPHYSICS::DIRECT_LIGHT_FROM_EMSHOWER; and
142  * - JPHYSICS::SCATTERED_LIGHT_FROM_EMSHOWER,
143  * respectively.
144  *
145  * The CDF tables can be produced with the script <tt>JMakePDF.sh</tt>:
146  * <pre>
147  * JMakePDF.sh -P
148  * </pre>
149  * (option <tt>-h</tt> will print all available options).
150  * Note that the script will launch a large number of processes (<tt>JMakePDF</tt> and <tt>JMakePDG</tt>)\n
151  * which may take a considerable amount of time to completion.\n
152  * On a standard desktop, all jobs should be finished within 1/2 a day or so.
153  *
154  * The same script should then be run with option <tt>-M</tt> to merge the PDF files, i.e:
155  * <pre>
156  * JMakePDF.sh -M
157  * </pre>
158  *
159  * CDF tables are obtained by running the same script with option <tt>-C</tt>, i.e:
160  * <pre>
161  * JMakePDF.sh -C
162  * </pre>
163  *
164  * The various PDFs can be drawn using the <tt>JDrawPDF</tt> or <tt>JDrawPDG</tt> applications.\n
165  * The tabulated PDFs can be plotted using the <tt>JPlotPDF</tt> or <tt>JPlotPDG</tt> applications.\n
166  * The tabulated CDFs can be plotted using the <tt>JPlotCDF</tt> or <tt>JPlotCDG</tt> applications.
