IRAC Science Data Simulator (ISDS)


Overview Installation Use Examples Known Limitations SSC Specific History



  1. Download the Simulator and Data files. The former contains the code and the latter contains a library of ground-test data and images used to make the sim.

  2. Choose a location in your system where these will reside. It is possible to do a shared, system-wide installation. 
    % mkdir /your_path/isds
% cd /your_path/isds

  3. Unzip and untar the packages in this location. 
    % gunzip iracsim20030709.tar.gz
% gunzip iracsim_images20030821.tar.gz
% tar -xvf iracsim20030709.tar
% tar -xvf iracsim_images20030821.tar

  4. There are detailed installation instructions for the package which should be read and followed (an older version is also packaged in the tar file). These instructions generally assume you have access to the root iraf account. If not, the following variances to the install instructions may help you install a system-wide installation:

    1. Make sure that the entire installation is readable/writeable by everyone: 
      chmod -R a+rwx /your_path/isds

    2. All users should add the following to their login.cl script: 
      set     irac            = "/your_path/isds/"
task    irac            = irac$irac.cl
reset  helpdb           = (envget ("helpdb") //
                         ",irac$lib/helpdb.mip")

    3. You will probably want to recompile IRACSIM as described in the installation instructions.

    4. You may need to recompile AOREXPAND, although this has been found to work well with the pre-compiled binary under Solaris 2.5.1, 2.6, and Solaris 8.
