ALMA Data Reduction Training Day: November 5, 2025
On Wednesday, 5 November 2025, we will host an ALMA Data Reduction Training Day in person in room CE.0.08.
The training will begin at 10:00 AM and continue into the afternoon with coffee breaks and an hour lunch break. The Allegro team will be presenting a series of talks and hands-on activities that cover: how to go from the archive to obtaining calibrated visibilities, a surface-level overview for calibration and self-calibration, using CASA, imaging, and exploring data cubes with CARTA. There will be sufficient time for Question & Answer sessions at the end of each section.
Several of the sessions will include a hands-on component that participants can follow along with. Information on how to connect to the Allegro workstations will be provided prior to the training day to the registered participants.

Directions to Leiden Observatory
Note that this is not the old observatory in the center of Leiden. The workshop will occur at the new Faculty of Science building (see image below). Leiden Observatory is located on the 3-4th floors of this building, and the Allegro offices are located on the 4th floor. The event will be held on the ground floor in room CE.0.08.
