The goal of this workshop is to introduce you to VLBI data reduction in CASA. We shall be using a European VLBI Network observation of 5 bright radio sources. We will 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. The tutorial was originally put together by Anita Richards (University of Manchester) and has been subsequently updated by Jack Radcliffe (SARAO / University of Pretoria).
IMPORTANT: if you are using the DARA computers these data will be located in ~/Data/EVN_continuum folder!
This tutorial requires around 20 GB of space so make sure you have enough room. The download links for each part are found below. Part 1 of this workshop should generate the $uv$ data for parts 2 and 3 so you just need to download the scripts. However, it may be necessary to use partially calibrated data if something goes wrong. These are provided below also.
|Part 1||Part 2||Part 3|
This tutorial is split into three parts. Use the hyperlinks below to get the the relevant section.
- Part 1: Basic calibration
- Part 2: Calibration & imaging of J1849+3024
- Part 3: Calibration & imaging of 3C345
This workshop is based upon the original workshop developed by Anita Richards (Uni. of Manchester) in 2016. The subsequent update has been conducted by Jack Radcliffe (SARAO/ Uni. of Pretoria) which has been influenced by Des Small's (JIVE) EVN CASA tutorial.
