Tutorials for the Very Long Baseline Array

CASA is offering increased VLBI support through a collaboration with the Joint Institute for VLBI ERIC (JIVE), where VLBI-specific CASA tasks are being developed and tested. The below VLBI CASA tutorials introduce the CASA environment and touch upon the visualization, calibration and imaging capabilities available, along with the scripting methods so that you can create your own calibration scripts for your own data.

Credits: These CASA tutorials represent publicly available materials developed by scientists from the University of Manchester, the Joint Institute for VLBI ERIC (JIVE), and the University of Pretoria/SARAO through funding from Development in Africa with Radio Astronomy (DARA). The materials are based upon a workshop developed by Anita Richards (University of Manchester) in 2016. The subsequent update has been conducted by Jack Radcliffe (SARAO/ University of Pretoria) which has been influenced by Des Small's (JIVE) EVN CASA tutorial. This EVN CASA tutorial also explains the step needed for pre-processing archiveal EVN data for use in CASA.

While implementation of VLBI data processing is an ongoing effort in CASA, we also include below two old AIPS tutorials on this topic.
