ALMA-VLBI QA2 Workshop– Leiden Lorentz Center, 24-28 February 2020
Allegro is hosting a QA2 training workshop for phased-ALMA data acquired during VLBI observations, which will be held in Leiden (the Netherlands), on February 24-28 2020.
VLBI is an observing mode offered since Cycle 4, and the first observations were conducted in Apr 2017. The QA2 process for VLBI projects is significantly more complex than the procedure for standard projects, requiring a close loop between ARCs, JAO and VLBI correlators.
The main goal of the workshop is to train ALMA astronomers so that the QA2 work load can be distributed across different regions. The training workshop will involve hands-on work on past cycles datasets.
This workshop is restricted to the trained QA2 analysts in ALMA Regional Centers (ARCs).

- SOC / LOC
The workshop will be held in the 2nd floor of the Snellius Building, room TBD. We will meet on Monday at 09:00 for welcome and introductions and will start the program at 10:00 am. On the first day we will have introductory talks. On the second day we will have four sessions “QA2 script overview”. On the third and fourth days we will have hands-on sessions with test datasets.
On the last day, we will work on documentation and discuss next steps.
We count to start everyday at 9:00 and finish at 17:30.
We look forward to seeing you!

There are regular buses from the Leiden Centraal station to the Lorentz Center (see the links below for more specific details if you will be coming by bus).
In alternative, you can look into renting a bike for your stay. You can pick this up at the railway station, at the rear (exit towards the hospital). Bikes costs 7.50 euro per day or 37.50 for a week.Near the workshop venue:
