VO Day Wien 2018

This VO Day will take part on 2018-02-22 to 2018-02-23

This course provides a basic introduction to the Virtual Observatory. The focus will be on access and analysis of table data, images and spectra. Participants will get to use Virtual Observatory tools like Topcat, Aladin, Splat and ADQL in hands-on sessions.

The VO Day will be held by Markus Demleitner (GAVO/AIP) and Hendrik Heinl (GAVO/ARI).

Please install the software we will use in the course in advance. All of these require Java to be installed on your machine. If you have problems during installation, don't hesitate to contact us.

  • JAVA as one of
  • TOPCAT
  • STILTS
  • Aladin
  • pyvo (there's a package python-pyvo in Debian stretch and friends; unless we get very far in the course, that should do)

You will need a laptop with internet connection.

Our goal of the workshop is that you leave with a set of skills that enable you to

  • retrieve data from the VO and how to fast access even large datasets with millions of rows/hundreds of columns
  • perform a query across multiple catalogues and cross-match them
  • exchange data between different VO tools
  • communicate with external VO and non-VO data services
  • how to use VO standards and tools and how to benefit from them
  • Do most of it in scripts using pyVO

There will be time to ask questions and to bring your own use cases. We encourage you to send your use cases to us in advance to:
