Astropy, PyVO and the Radio realm
2021-10-24, 19:00–21:40, Grand Ballroom

In the past years, VO standards were widely accepted and spread and many
astronomers get more and more familiar with standards and protocols like
Cone Search, SAMP and TAP/ADQL. Being skilled in these in combination with
Astropy and PyVO opens unlimited opportunities to find, to access and to
combine different datasets for further analysis.

In this tutorial the participants will learn how to use PyVO and ObsTAP
to find services and to explore the data on these services, they will
use Daralink and SODA to perform cutouts on large images, and eventually
use PyVO and Astropy to write a SAMP handler to combine functionality of
TOPCAT and Aladin with PyvO.
The cutouts will be performed on the Astron data service on data derived
from LOFAR.
The cutouts will be performed on the Astron data service on LOFAR
derived data.

We don't expect participants to be experts in above fields after this
tutorial, but to scratch on the surface of how useful these tools are and where to turn if they want to get deeper knowledge. In particular this should

  • TAP/ADQL and related special Obscore services
  • PyVO for data discovery and data access
  • How to read a standard document to develop against this standard

The used software will be:
Python 3.6 (or newer), Astropy, PyVO, Topcat and Aladin. We will provide Python scripts in a github repository.
