The European ARC Network invites users to a second I-TRAIN on VLBI data using ALMA as a phased array on 16 May at 10:00 CET (link to Zoom).

This tutorial will provide an introduction to accessing and dealing with VLBI data from networks which include ALMA as a phased array. We will first cover accessing phased data and what is on the ALMA archive.  Then ALMA's role in the Global Millimeter VLBI Array (GMVA), how to obtain PI and/or archival GMVA data, and how to calibrate them will be discussed. Finally, we'll look at EHT data, how to obtain those publicly available datasets, and how to calibrate them.

The duration of this training session will be about 1.5 hours followed by a Q&A session. If you have any questions, please contact Kazi Rygl at kazi.rygl@inaf.it.

Tutors: Micheal Jansen, Georgios-Filippos Paraschos, Kazi Rygl

Note: The presentation will be recorded and an edited version of the recording will be posted in the Science Portal after the session. The interactive Q&A will not be recorded.
