[Difx-users] Announcing the SFXC Software Correlator workshop {External}

[Marjolein Verkouter]

SFXC VLBI Software Correlator Workshop
September 22/23, 2025

Apologies if you receive this announcement multiple times - and feel free to forward it to anyone who you believe might be interested.

This workshop is aimed at individuals interested in using the Super FX Correlator ("SFXC") for software correlation of data from their own VLBI instruments (or other long-ish baseline radio interferometers), as well as scientists who want to exploit SFXC's advanced features by doing their own correlation.

Workshop Overview

The workshop will take place over two days, mixing theory and practical hands-on sessions at JIVE's host institute ASTRON in Dwingeloo, The Netherlands. There will also be room for discussion about future developments of SFXC (including GPU-based correlation) and suggestions for improving the SFXC documentation.

Limited Participation

The number of participants is limited to twenty (20) to enable a useful teacher-to-student ratio for the practical sessions. If we receive more than 20 registrations by the registration deadline of May 25th 2025, we will select participants based on the survey in the registration form (see link at the bottom of this page).

Selected participants will receive confirmation before June 6th 2025. Please hold off making travel arrangements until your participation has been confirmed!
Course Content

Lectures will be delivered by the SFXC developers, JIVE's in-house experts, and external users already using SFXC for their own data processing. Topics will include:

  *   Correlator models
  *   Correlation preparation
  *   Mixed-bandwidth correlation
  *   Geodetic correlation

  *   Real-time correlation
  *   Post-processing of correlator output
  *   Using SFXC for space science
  *   Using SFXC for FRB localization

Prerequisites

We expect each participant to:

  *   Bring a laptop with an ssh client installed
  *   Have experience with radio interferometry
  *   Be familiar with a UNIX/Linux shell command-line environment
  *   Have programming experience in Python

Practical Information

The workshop is offered free of charge, but no travel, lodging, sustenance, or other form of financial support will be available. A block booking of hotel rooms at the nearby Hotel de Borken<https://www.hoteldeborken.nl/en/> has been made and bicycles will be provided to commute between the hotel and ASTRON's premises.

Code of Conduct

JIVE and ASTRON are dedicated to providing an inclusive and safe environment for everyone: employees and visitors; therefore this workshop is covered by the Dwingeloo code of conduct<https://www.jive.eu/dwingeloo-code-of-conduct>.
