*** videos from Monday and Tuesday are now available from http://astro.dur.ac.uk/ps1sc_workshop/video/ ***
To operate
- go to: http://evo.caltech.edu/evoGate/index.jsp
- click on recording player
- Once the EVO recording player is working, open the relevant url for the session needed, e.g.: http://astro.dur.ac.uk/ps1sc_workshop/video/Monday_afternoon_1.evx
- Unfortunately the last session on Tuesday has sound only, and none of the presentations on Wednesday were recorded (sorry!).
