March 19-23, 2018, at Lorenz Center in Leiden, this workshop brings together experts and interested radio astronomers to learn how to produce high resolution images with the Low Frequency Array (LOFAR) and to discuss and finalize the details for implementing a pipeline to do this on a large scale to post-process already existing observations. During this week tutorials for the novices will be provided and discussions with all interested parties on how to implement the specialized pipeline to post-process LoTSS data will be conducted.
