ALMA Data Reduction Training Day: November 30, 2021

Following the 5th Netherlands ALMA Science Day, on Tuesday, November 30, 2021, we will host an ALMA Data Reduction Training Day that will follow a hybrid format: all presentations and hands-on activities can be followed online, but we also have physical workspaces available in Leiden for those who wish to make use of these.

The training will begin at 9 AM and continue into the afternoon with coffee breaks and an hour lunch break. In the first part, the Allegro team will be presenting a series of talks that cover the following topics: how to go from the archive to obtaining calibrated visibilities, calibration, imaging, self-calibration, and analysis tools. There will be a short Question & Answer session at the end of each talk (approximately five minutes), with a longer general Q&A session at the end of the talk series.

In the afternoon, we will host an interactive workshop during which we will take you through the following topics:

  • Inspection of data quality
  • Continuum subtraction
  • Basics of imaging
  • Self-calibration
  • Advanced imaging techniques
  • Analysis tools

The workshop will make use of CASA Guides that are readily available online, and we will provide you with the dataset we will be using on the day of the workshop.

Directions to Leiden Observatory

Note that this is not the old observatory in the center of Leiden. Instructions on how to get to Leiden Observatory, including transportation from Schiphol Airport or the central trains station, can be found here. Note that these instructions specify the route to the Lorentz Center, which is in the building on the right in the photo below (Oort building). The event will be held in the joining taller building –  Huygens building. Leiden Observatory is located on the 4-5th floors of both buildings, and the Allegro offices are located on the 11th floor of the Huygens building.

Locations inside the building

Workspaces reserved for the ALMA Data Reduction Training Day on November 30, 2021 are located in room HL-111 on the 1st floor of the Huygens building. There is a reception at the entrance of the building where they can provide you with directions.
