Computing and software
First two most important things:
- Make backups and save your data (e.g. with tar/zip and rsync/scp)! All home directories will be permanently deleted when the container is removed!
- If you use iraf, start and use iraf only in ~/iraf or its subdirectories, i.e. type
cd ~/iraf. Otherwise iraf will not work (more about iraf later)
Connecting to the container computer
You can use x2go to connect to the container. Usernames and passwords will be provided by the course organizers.
Connecting with x2go
For information on the installation of x2go, see: https://wiki.x2go.org/doku.php/doc:installation:x2goclient
To connect to the container with x2go, please use XFCE as the session type. Here are typical settings (of course use your user account):
Using SSH to connect
In case of ssh, the command is
ssh -Y USER@tube.utu.fi
on Linux.
Setting up software
EsoReflex
To activate EsoReflex software, write the command esoreflex in a terminal.
Iraf
Note: you have to do the following every time you open up a new window!
1) To activate iraf related software, in your current terminal, write the command iraf27 and cd ~/iraf
1b) If this is the first time you use IRAF on the container, write the command mkiraf in your iraf27 terminal in the iraf folder. It will ask about the terminal type, write xgterm and this will create a login.cl file to the iraf folder.
2) In the iraf folder with the iraf27 terminal write the command xgterm &
3) Write the command cl to your newly opened xgterm terminal to start iraf.
4) To open ds9 write the command ds9 & in the iraf27 terminal.
Note, that you have to process your data within your iraf folder or any subfolder you create there.
Starlink Gaia
To activate starlink (https://www.eaobservatory.org/~s.graves/WWW/) software, e.g. gaia, write the command starlink and then gaia
Fv
To activate Fv software, write the command iraf27 and then fv
Log Out or Exit
When you finish your session on the course container, you can exit just by killing the remote desktop client window. You will return to the same desktop when you log in again. You can log out from the session via Applications → Log Out → Log Out.
Returning to x2go
Sometimes when you return to x2go session especially if the session is still running in another client, the client asks whether to suspend or terminate the session. Usually you want to suspend and then resume. terminate will kill the running session and start a new.
Enjoy!
