How to obtain the Hydra CTIO Simulator
First, download the Simulator:
Software binaries are available to run under Linux and Solaris. The latest versions will be found in hydrasimLinux for Linux and in hydrasimSolaris for Solaris. Both versions can also be found in the Tucson mirror of the CTIO ftp site (updated nightly). Current version of the software is 4.0.2.
Install the software:
First, be sure you are running the c-shell or one of its derivatives (e.g. tsch). If you are running the bash shell, you can change to the c-shell using the command chsh -s /bin/csh Put the tar file in your home directory, change to your home directory and then
Under Linux run
tar -xf hydrasimLinux.tar
Under Solaris run
tar -xf hydrasimSolaris.tar
Now change to subdirectory "/Hydra/bin" and execute "~/install.org". This is a script that will create three sub-directories (fiblogs, fields & stdfields) in your home directory. Copy the file "~/Hydra/bin/sample.fiborg" to .fiborg in your home directory as well. Then include in the "set path" command of either your ".login" or ".cshrc" file the following path:
Also, add the folowing line to your .login or .cshrc file to source the .fiborg and set the environment:
Log out and back in to allow the new path to be activated or type "source ~/.login" (or source ~/.cshrc or whatever is your particular rc file). If you chose not to decompress and de-tar the downloaded file in your home directory change variable FIBHOME in file ".fiborg" to reflect the new location of the software as well as the bin path for the "set path" command.
Start the simulator with the command: hydrasim
Two windows will appear. One is a simple command line window (CLI/Script Tool window) and the other is a window showing a graphical representation of the fibers and the focal plate. It also includes various information about the current star field and status. The terminal window used to launch the program will be used as a console.
