Participants are expected to bring their own laptops, equipped with CASA pre-installed.
Please download and install CASA Release 5.6.0 on you laptop computer.
Datasets, scripts, presentations, etc.
L1+L2 Introduction to interferometry:
Please also download the mp3 file BN.mp3
to your smartphone or mp3 player, and bring it together with headphones to the lecture. (Not mandatory, but it will be used for a little interferometry experiment at the beginning of L1).
T2 Introduction to writing a proposal:
Presentation (Laing): T2.pdf
L3+T3 Getting started with real data, interactive:
This session introduces the general form of a radio observation (scans, fields, spectral windows, etc). We will do some plotting, flagging, work with the Measurement Set browser, and briefly introduce TaQL.
The session will use the data from the Calibration session (L5+T4) below.
and open 3C277.1_cal2019.html in a browser in the HTML directory. This then gives instructions and links to the data and scripts.
L6+T5 Introduction to imaging, interactive:
L7+T6 Proposals and observing planning, interactive:
Presentation (Laing): L6_T7.pdf
L10+T8 Very long baseline interferometry, interactive lecture and tutorial:
This session consists of three lectures and a tutorial. The lectures are interactive and include exercises all based on the same data, which can be downloaded here: EVN_continuum_pt1.tar.gz.
on EVN continuum: DARA tutorial (link to Jodrell Bank). Note that the data set labeled Part 1: Data + scripts (1.7 GB) is the same as the file EVN_continuum_pt1.tar.gz (see link above).
T9A Advanced tutorial Metre/wide-field (LOFAR):
T9B Advanced tutorial Centimetre/polarisation:
T9C Advanced tutorial Centimetre/VLBI:1. Data, scripts and presentation can be download from this DARA tutorial (link to Jodrell Bank). Please download the data set labeled NGC660 data (1.7 GB), and unpack it as instructed in the first lines of the tutorial. For this tutorial the participants will need to make sure that their laptop has ~10 GB of free disk space.
2. Download the file ea054_t9c_small.tar.gz. (5.7 GB, but 25 GB when unpacked, needs at least that much again to do the processing)
T9D Advanced tutorial Millimetre/spectral line (ALMA/NOEMA):
This tutorial consists of three parts with the following corresponding presentations:
You will need the following files:
The following link directs you to large ALMA example datasets (~100 GB). You do NOT need to download these large files to follow the tutorial. We provide the links here only for those interested in retrieving the complete dataset (including all products): T9D.tar (~100 GB).
T9E Advanced tutorial mm/VLBI:
Note: The rPICARD software used during this tutorial requires a special CASA version with advanced VLBI tools. When using Linux or a virtual environment, multiple CASA versions can be installed at the same time. The CASA 5.6.0 version can be kept as the default CASA version when its casa executable is added to your PATH. Windows and MacOS users can use the docker image or virtual machines provided by the Onsala Space Observatory.
L11 Useful Python tools:
This lecture will introduce a selection of tools and Python modules that can be useful in radio astronomy.
