Square Kilometre Array Science Data Challenge 1

Abstract

The Square Kilometre Array (SKA, https://skatelescope.org) will be the world's largest radio telescope. SKA Science Data Challenges will be regularly issued to the community as part of the science preparatory activities. The purpose of these challenges is to inform the development of the data reduction workflows, to allow the science community to get familiar with the standard products the SKA will deliver, and optimise their analyses to extract science from them. These challenges may consist of real data from currently operating radio facilities or of simulated SKA data. The purpose of this document is to provide information on how the SKA Science data challenge #1 (SDC1) has been produced and to set the challenge for the community. For more information on how to take part in the challenge and to download the data see https://astronomers.skatelescope.org/ska-science-data-challenge-1/
