ET Workshop Summer 2013

Summer Einstein Toolkit Workshop 2013
Users workshop
The users workshop is part of the CGWAS and will be held on the last day of the summer school (Friday). Currently the programme lists introduction to numerical relativity, an introduction to the ET and two hands-on sessions. The big hands-on session from last year was too technical and should be reworked if used at all. Instead we could consider running a very short head-on nsns run and analysing the data. The runs takes ~20min at a ridiculously low resolution, but might be sufficient to shows how it's done.

Vagabond Inn, Pasadena, 1203 East Colorado Blvd., Pasadena, CA 91106, Phone (626) 449-3170, http://www.vagabondinn.com, $79.00 double bed (one or two persons), rate on website differs, best to call and mention Caltech. |
| Transportation - Hotel | There are many possible ways of getting from the airport to Pasadena:
At any terminal at LAX, you will find departure platforms for all of the above transportation systems just outside the terminals. The FlyAway Bus + Metro is usually very convenient. To get on it, just wait by the blue sign that says "FlyAway Busses". Wait until a FlyAway Bus with sign "Union Station" arrives (it departs every ~30min). Jump on it and go until Union Station (its only and final destination). You pay $7 upon arrival (they have change if you don't exactly have $7). At Union Station, go to the platform that says "Metro Gold Line". Pay $1.50 at the ticket machine (one way ticket). Take the Metro Gold Line (direction "Sierra Madre Station") and exit at "Lake Station" (Caltech or Vagabond Inn) or "Allen Station" (best for the Saga Motor Hotel). Check out google maps for further info. Here's a link to Metro Gold Line, including a link to this trip planer (it also knows about FlyAway busses). |
| Transportation - Workshop | walking distance, directions. |
| Food options | Chandler's on campus, Ernie's food truck (times), restaurants on Lake, anything on Colorado. |
