The fakerad software is distributed by www.asc.rssi.ru It is located in the "/radioastron/software/fakerad/" subdirectory. ------------------------------------------------------ IMPORTANT: At present the software "FAKERAD" runs only under 32 bit Linux workstation in X windows with C shell script. ------------------------------------------------------- 1. Launch csh or tcsh if you use another shell. All procedure runs under C shell. 2. Copy all files from the given directory to your computer. 3. You must unpack "fakeradlib.tgz" by tar xvfz fakeradlib.tgz 4. Then copy thus obtained directory "fakeradlib" to your home directory. 5. You shall provide (acting under root account) the symbol reference to this directory: ln -s ~/fakeradlib /usr/local/fakerad 6. And do not forget to write path in the configuration file ".cshrc": set path=($path /usr/local/fakerad) 7. Then, unpack the next file "fakerad.tgz" into your home directory: tar xvfz fakerad.tgz Now you have the directory, where the fakerad will be started by "run" command. 8. You must be sure that PGPLOT software is installed at your computer. One may get PGPLOT at ftp://ftp.asctro.caltech.edu/pub/pgplot5.2.tar.gz One of the most common errors when running fakesat_menu is for the menu to be appear but with no words. The reason for this is that PGPLOT cannot find the "grfont.dat" font file. To remedy this situation edit the "run" C shell script end set the PGPLOT_FONT environmental variable to the pathname of the "grfont.dat" file. 9. Orbit Copy ASCII-file representing the current version of orbit to the "orbit" subdirectory located in "fakerad". In order to activate selected file with orbit you must provide the symbol reference indicated to selected orbit-file by ln -s ~/fakerad-latest/orbit/RAXXXXXX-XXXXXX.org ~/fakerad/orbit/ra_orbit where RAXXXXXX-XXXXXX.org is the name of the file containing orbit data. Now, everything is ready. (In the current distribution of fakerad, the orbit is already provided and is properly linked to.) The run C shell script can perform several functions. To find out more about "run" type run -h. In order to aid novice users a simplified version of the interactive menu system has been produced. This enables only a limited number of parameters to be changed and options to be run. This should be quite sufficient for most users. Indeed it can be quite dangerous for novice users to change parameters that the VLBI observer has no control over. This simplified version of the menu is the default. A more advanced user can obtain the full range of options by typing "run -c" instead of simply "run". All the parameters that can be viewed on the interactive menu are stored in the menu_defaults file. If this file should become corrupted fakesat_menu will not work correctly. As a precaution every time fakesat_menu starts it copies the menu_defaults file to a backup copy called menu_defaults.1. Thus, if the menu_defaults file becomes corrupted or you accidently delete it, you can rectify the situation by copying the menu_defaults.1 file to the menu_defaults file. 9. To use "FAKERAD Reference Manual" one must hale "LaTex" installed. I wish you successful job.
