- Your "home directory" will be nfs-mounted from the dept. file server so that files you
create here will be available on other dept. computers.
Hint: Create a subdirectory to keep your Optics Lab files separate from others.mkdir optics
and then on login, your 1st command should becd optics
any new files created will now been in this sub-directory.

Known Bug with UBUNTU
How to start any program from UBUNTU system. Left click on dash-home button in toolbar. This enables a search for applications. The three applications are xawtv, system monitor (for closing crashed programs), and terminal. Now, on some of the computers when you start xawtv it crashes. On first attempt you get a green screen and software hangs. Then you go to task manager and shut that down. On second attempt you get black screen. Shut down with task manager and on third attempt, it works.
Plotting and Analysis
- Images and graphs can be printed on the physics printer using the following commands:
NB -- printing directly from the optics systems is not configured at present. use a shell on ssh2.phas.ubc.ca a.k.a. tau.phas.ubc.ca to print files. iessh tau lpr filename
- There are a number of analysis tools available:
