Participants are expected to bring their own laptops, equipped with CASA pre-installed.
Software packages
CASA
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 this
mp3 file 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 (added 2019-10-07)
L3+T3 Getting started with real data, interactive:This session will introduce 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.
Open 3C277.1_cal2019.html in a browser in the HTML directory. This then gives links to the data and script.
L6+T5 Introduction to imaging, interactive:
The data and scripts for the imaging tutorial can be downloaded from this
DARA tutorial.
Please download the data set labeled as 3C277.1 data (pt2 only) (464MB).
L7+T6 Proposals and observing planning, interactive:Presentation
L10+T8 Very long baseline interferometry, interactive:
The data for each part should be stored in their own directory and unpacked.
- Very Long Baseline Interferometry:
presentation (244 MB; added 2019-10-08)
T9A Advanced tutorial Metre/wide-field (LOFAR):
The
ERIS school will provide access to computing resources for those doing the LOFAR tutorial. You will need a laptop with a web browser (e.g., a reasonably recent version of Firefox or Chrome).
T9B Advanced tutorial Centimetre/polarisation:
T9C Advanced tutorial Centimetre/VLBI:1. The large (1.7 Gb) dataset from the
DARA spectral line tutorial, unpacked 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 will consist of three parts. You can find the corresponding presentations at:
You will need the following files:
The following link directs you to large ALMA example datasets (~100GB). 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):
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.
T10 Proposal presentations:
