Processing Radio Astronomical Data Using the PROCESS Software Ecosystem

Souley Madougou, Hanno Spreeuw, Jason Maassen
2020 Computing and informatics  
In this paper we discuss our efforts in "unlocking" the Long Term Archive (LTA) of the LOFAR radio telescope using the software ecosystem developed in the PROCESS project.  ...  The LTA is a large (> 50 PB) archive that expands with about 7 PB per year by the ingestion of new observations.  ...  Acknowledgements This work is supported by the "PROviding Computing solutions for ExaScale ChallengeS" (PROCESS) project that has received funding from the European Union's Horizon 2020 research and innovation  ...

Building a scalable global data processing pipeline for large astronomical photometric datasets [article]

Paul Doyle
2015 arXiv   pre-print
Astronomical photometry is the science of measuring the flux of a celestial object.  ...  Since its introduction, the CCD has been the principle method of measuring flux to calculate the apparent magnitude of an object.  ...  Once a node is running, it checks the queue for unlocked files and locks them as already described.  ...
