|
---|
17 | More than one software developer are involved in the progress of Software
|
---|
18 | for the MAGIC telescope. Because the developers are distributed all over
|
---|
19 | Europe, a version control system is needed. There exists more than one
|
---|
20 | possibility of such version control systems, but for the beginning we take
|
---|
21 | CVS ( Concurrent Versions System ).
|
---|
22 | <p>CVS is a version control system, which allows you to keep old versions
|
---|
23 | of files (usually source code), keep a log of who, when, and why changes
|
---|
24 | occurred, etc., like RCS or SCCS. Unlike the simpler systems, CVS does
|
---|
25 | not just operate on one file at a time or one directory at a time, but
|
---|
26 | operates on hierarchical collections of directories consisting of version
|
---|
27 | controlled files. CVS helps to manage releases and to control the concurrent
|
---|
28 | editing of source files among multiple authors. CVS allows triggers to
|
---|
29 | enable/log/control various operations and works well over a wide area network.
|
---|
30 | <p>CVS keeps a single copy of the master sources. This copy is called the
|
---|
31 | source ``repository''; it contains all the information to permit extracting
|
---|
32 | previous software releases at any time based on either a symbolic revision
|
---|
33 | tag, or a date in the past.
|
---|
34 | <p>For CVS updates, more information on documentation, software related
|
---|
35 | to CVS, development of CVS, and more, see:

|

42 | <p>The single copy of the master source for all MAGIC software is held
|
---|
43 | in the repository on a single (security reasons) linux computer in Max-Planck-Institut
|
---|
44 | für Physik in Munich. As a remote developer you must declare the environment
|
---|
45 | variable.

---|
46 | <p><b><font color="#33FF33">setenv CVSROOT :ext:pchegra4.mppmu.mpg.de:/CvsRepository </font></b>
|
---|
47 | for tcsh (use the syntax of your shell)
|
---|
48 | <p>The access from other computers is still under construction and tests.
|
---|
49 | If you want access please inform<a href="mailto:harald@hegra1.mppmu.mpg.de">
|
---|
50 | Harald Kornmayer </a> in Munich. For more details about the structure

|

56 | <p>All developers should use CVS commands for further development. I set
|
---|
57 | up different projects of software development. Please take only the source
|
---|
58 | file from the repository which are necessary for the project you want to
|
---|
59 | work on. Please don't work on to much projects in parallel. If you are
|
---|
60 | planning to do bigger changes create your own development branch. But don't
|
---|
61 | wait to long with committing.

64 | <br><font color="#FF0000"><font size=+2>Projects</font></font>
|
---|
65 | <p>The software is separated in different software projects. This projects
|
---|
66 | are:
|
---|
67 | <br>
|
---|
68 | <blockquote><font color="#CC6600"><font size=+1> Mmcs (Magic Monte
|
---|
69 | Carlo Simulation )</font></font>
|
---|
70 | <br>This is the adapted CORSIKA code for calculating air showers.
|
---|
71 | <p><font color="#CC6600"><font size=+1>Reflector</font></font>
|
---|
72 | <br>With this program you can track the cerenkov photons generated by Mmcs
|
---|
73 | to the camera plane. So all the geometry of the telescope is inside this
|
---|
74 | program.
|
---|
75 | <p><font color="#CC6600"><font size=+1>Camera</font></font>
|
---|
76 | <br>To change the information of the cerenkov photons to FADC counts you
|
---|
77 | have to use the camera program. This program contains a lot of different
|
---|
78 | other sources that are also used by the reflector or the Evita project.
|
---|
79 | <p><font color="#CC6600"><font size=+1>Evita (EVent Imaging Tool for Analysis)</font></font>
|
---|
80 | <br>To display one event use this nice Gui package.
|
---|
81 | <p>.......
|
---|
82 | <br> </blockquote>
|
---|
83 | It is obvious that some source code of a given directory is part of different
|
---|
84 | projects. I.e. the directory include-MC is a part of the reflector and
|
---|
85 | the camera project.

89 | <br>
|

90 | <ol>
|
---|
91 | <li>
|
---|
92 | Continue with development of existing projects</li>
|
---|
93 |
|
---|
94 | <br>command: cvs checkout <i>project</i>
|
---|
95 | <br>Then you will get all the directories that are necessary for compiling
|
---|
96 | the given project. So go first in the directory with the Makefile and try
|
---|
97 | to compile it. Then you can start with working on the source files. At
|
---|
98 | the end of your work you will have modified source files.
|
---|
99 | <br>
|
---|
100 | <li>
|
---|
101 | Check the status of the files in your directory</li>
|
---|
102 |
|
---|
103 | <br>command: cvs status
|
---|
104 | <br>Then you will get a long list with information of all files in this
|
---|
105 | directory and all sub directory.
|
---|
106 | <br>If you want to see only the names of the modified files use the
|
---|
107 | <br>command:cvs status | grep odi
|
---|
108 | <br>
|
---|
109 | <li>
|
---|
110 | See differences of your files and the repository</li>
|
---|
111 |
|
---|
112 | <br>command: cvs diff <i>[filename]</i>
|
---|
113 | <br>This will show you the changed you did.
|
---|
114 | <br>
|
---|
115 | <li>
|
---|
116 | Commit your changes to the repository</li>
|
---|
117 |
|
---|
118 | <br>command: cvs commit [<i>filename]</i>
|
---|
119 | <br>The changes you made will then be in the repository and are available
|
---|
120 | for all other developers.
|
---|
121 | <br>
|
---|
122 | <li>
|
---|
123 | Remove all your files</li>
|
---|
124 |
|
---|
125 | <br>command: cvs release -d [filename]
|
---|
126 | <br>Do this in the most upper directory (There you can see i.e. MagicSoft.).
|
---|
127 | If CVS find some altered files it will not deleted all immediately. But
|
---|
128 | if you have no altered files say yes and delete all the files and directory
|
---|
129 | you worked on. So you are always sure that there is no old or changed version
|
---|
130 | of a project.

395 | directory, mainly based on the work of Jose Carlos Gonzales.

397 | <blockquote><a NAME="Anchor_Reflector"></a><font color="#CC33CC"><font size=+2>Reflector</font></font>
|
---|
398 | <br> Here you find the source code of the reflector program. This
|
---|
399 | is written to read the CORSIKA (Mmcs) output. With this data you can simulate
|
---|
400 | the behavior of the MAGIC mirrors. But to compile and run the program some
|
---|
401 | other sub directories are needed.
|
---|
402 | <p><a NAME="anchor_Camera"></a><font color="#CC66CC"><font size=+2>Camera</font></font>
|
---|
403 | <p><font color="#330000"> In this directory are all the files of the
|
---|
404 | camera program. The camera program is calculating the response of each
|
---|
405 | photo multiplier of the camera. At the end we get the number of ADC count
|
---|
406 | for each time slice of each pixel. In the previous there were also some
|
---|
407 | smaller calculations of the camera pixels in it.</font>

408 | <p><a NAME="Anchor_include-CORSIKA"></a><font color="#CC33CC"><font size=+2>include-CORSIKA</font></font>
|
---|
409 | <br>Here you can find a implementation to read the CORSIKA output. This
|
---|
410 | classes are needed by the reflector program.
|
---|
411 | <p><a NAME="Anchor_include-MC"></a><font color="#CC33CC"><font size=+2>include-MC</font></font>
|
---|
412 | <br>Here you can find a implementation to write and read the output of
|
---|
413 | the reflector program. This classes are needed by the reflector and the
|
---|
414 | camera program.
|
---|
415 | <p><a NAME="Anchor_include-GENERAL"></a><font color="#CC33CC"><font size=+2>include-GENERAL</font></font>
|
---|
416 | <br>Here you can find some header file that are needed by reflector and
|
---|
417 | camera. For example the declaration of the runlib is found here.
|
---|
418 | <br>
|
---|
419 | <p><a NAME="Anchor_include-MTrigger"></a><font color="#CC66CC"><font size=+2>include-MTrigger</font></font>
|
---|
420 | <br>Studies of the trigger behavior are very fundamental things. The simulation
|
---|
421 | of the trigger is a part of the camera program. All the methods are put
|
---|
422 | in the Classes (called MTRigger ) in this directory.
|
---|
423 | <p><a NAME="Anchor_DetData"></a><font color="#CC33CC"><font size=+2>Data</font></font>
|
---|
424 | <br>All the different data files for the simulation tools reflector and
|
---|
425 | camera are in this directory. For example the geometry of the MAGIC telescope
|
---|
426 | is stored in magic.def or the data of the focal points is stored in focal.dat.
|
---|
427 | <p><a NAME="Anchor_lib"></a><font color="#CC33CC"><font size=+2>lib</font></font>
|
---|
428 | <br>Here you find the ranlib that is used by reflector and camera.</blockquote>

430 | <a NAME="Anchor_include-Classes"></a><font color="#CC66CC"><font size=+2>include-Classes</font></font>
|
---|
431 | <p>In this directory you can find all Classes (C++ and hopefully OOP )
|
---|
432 | that are used for simulation and for analysis. An example is the RawDataFormat
|
---|
433 | used in the Analysis and the Camera programs. The Classes are MRawPixel,
|
---|
434 | MRawEvt, MRawMc .....

---|
435 | <p><a NAME="Anchor_Analysis"></a><font color="#CC66CC"><font size=+2>Analysis</font></font>
|
---|
436 | <p>In this directory you can find all Programs to analyze data of MAGIC.
|
---|
437 | Here you will find tools to look on single Events, to calculate the Hillas
|
---|
438 | parameters and to find the periodicity of one special source. (But all
|
---|
439 | this is still under construction!!!! Here the must development is needed
|
---|
440 | in the future!!!)
