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.

(If the Jodrell Bank web site is unavailable, try instead this pdf version: L6+T5_DARA-3C277.1-e-MERLIN-Workshop_200330.pdf, and the data set 3c277_workshop_pt2_only.tar.gz.)

L7+T6 Proposals and observing planning, interactive:
Presentation (Laing): L6_T7.pdf.

T7 Self-calibration:
Data, scripts and presentation can be download from this DARA tutorial (link to Jodrell Bank).
(If the Jodrell Bank web site is unavailable, try instead this pdf version: T7_Self-calibraion-of-3C277.1_200330.pdf, the presentation (Radcliffe, Richards) self_calibration_ERIS19.pdf, and the data set ​3c277_workshop_pt2_only_ERIS2019.tar.gz.)

L8 Polarisation:
Presentation (Martí-Vidal): ERIS-2019_L8.pdf.

L9 Spectral line interferometry:
Presentation (Johnston): Lecture_spectral_line_2019.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.
Lecture 1: Presentation on VLBI science and calibration  (van Bemmel)VLBI_lecture_IVB_v4.pptx.
Lecture 2: Presentation on pipeline rPicard (Janssen)2019_ERIS_DARAtutorial_phasecalib.pdf.
Lecture 3: Presentation on VLBI imaging (Spingola)L10_lecture_part_3.pdf. Additional scripts and pre-formatted data discussed in this lecture (1.3 GB)L10_lecture_part3.tar​.
Tutorial 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).
(If the Jodrell Bank web site is unavailable, try instead this pdf version: L10+T8_DARA-EVN-Continuum-Workshop_200330.pdf​.)
As an alternative, the JIVE tutorial for EVN continuum calibration​ is a good place to start.

T9A Advanced tutorial Metre/wide-field (LOFAR):
Presentations (Williams)DIcal_prefactor_part1.pdf and DDcal_factor_part1.pdf​.

T9B Advanced tutorial Centimetre/polarisation:
Presentation (Richards): ERIS2019_T9B_polarisation_amsr.pdf.
3C277.1 data (630 MB): small_avg_pol1.ms.tar.

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.​
(If the Jodrell Bank web site is unavailable, try instead this pdf version: T9C_DARA-Spectral-Line-Workshop_200330.pdf and the data set NGC660_tutorial.tar.gz.)
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:
Presentation (Toribio, König, Tafoya, Muller, Johnston): TWHya_tutorial_reduction_2019.pdf​.
Presentation (Toribio, König, Tafoya, Muller, Johnston): TWHya_tutorial_imaging_2019.pdf.
You will need the following files:
T9D_TW_Hya.tgz (1.7 GB)
T9D_TW_Hya_corrected.tgz (ONLY needed if you don't finish the first part of the tutorial;1.3 GB)
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:
Presentation (Jenssen, Martí-Vidal): 2019_ERIS_rPICARDtutorial_mmVLBI.pdf.
Data and scripts (1.9 GB): S6096B.tar.gz.
Installation instructions: rPICARD_install_notes.txt.
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.
Presentation (Bourke): ERIS-L11-sbourke-PythonTools.pdf.
