Date and Location
Wednesday 3 July 2018
The workshop will be held at the National Astronomy Meeting 2019 (NAM2019, https://nam2019.org/ ) at Lancaster University https://www.lancaster.ac.uk/ .
Participant Q&A:
At the end of each session there will be some time for the attendees to ask about the usage of the presented tools for personal cases.
Examples shown during the meetings:
- API access with python to Gaia (Jupyter).
- API access with python to Gaia (python script).
Background Material
The Gaia DR2 data can be found at:- ESA/ESAC: http://gea.esac.esa.int/archive/
- CDS: http://cdsweb.u-strasbg.fr/gaia
- ARI: http://gaia.ari.uni-heidelberg.de/index.html
- AIP: https://gaia.aip.de/
- ASI/ASCD: http://gaia.asdc.asi.it/
- ADQL Gaia DR1 cookbook: https://gaia.ac.uk/data/gaia-data-release-1/adql-cookbook
- CDS ADQL quick info sheet: http://tapvizier.u-strasbg.fr/adql/help.html
- GAVO ADQL help sheet: http://docs.g-vo.org/adqlref/adqlref.pdf
- ARI ADQL tutorial page: http://docs.g-vo.org/adql-gaia with associated slides http://docs.g-vo.org/adql-gaia/html/pop.pdf
Installing the 'helper' clients:
Topcat (recent version, preferably v4.6+): see http://www.star.bris.ac.uk/~mbt/topcat/#install
Aladin (recent version, preferably v9+): see http://aladin.u-strasbg.fr/java/nph-aladin.pl?frame=downloading
Java is required by Topcat and Aladin: any recent java version is OK, but Oracle/Hotspot Java SE (from https://www.oracle.com/technetwork/java/index.html) is recommended rather than OpenJDK. On linux you can run “java -version” to see which you have.
Instructions for installing Python
If you don’t already have a Python (scientific) stack on your computer, you can easily install the Anaconda stack. This comes with “batteries included”, and comes packed with numpy (numerical python), scipy (scientific python), Astropy (astronomical Python library), and matplotlib (a plotting library).
You can get the Python 2.7 or Python 3.5 Anaconda version from:
https://www.anaconda.com/distribution/
If you don’t know which Python version to chose, then select Python 3.5 (graphical or command line installer -- either is OK).
