TL;DR: The LOFAR Two-metre Sky Survey (LoTSS) as mentioned in this paper is a deep 120-168 MHz imaging survey that will eventually cover the entire northern sky, where each of the 3170 pointings will be observed for 8 h, which, at most declinations, is sufficient to produce ~5? resolution images with a sensitivity of ~100?Jy/beam and accomplish the main scientific aims of the survey, which are to explore the formation and evolution of massive black holes, galaxies, clusters of galaxies and large-scale structure.

TL;DR: The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168 MHz survey of the entire northern sky for which observations are now 20% complete as discussed by the authors.

TL;DR: In this article, a new calibration scheme, which is called facet calibration, is presented to obtain deep high-resolution LOFAR High Band Antenna images using the Dutch part of the array.

TL;DR: In this article, the authors presented deep LOFAR observations between 120 and 181 MHz of the "Toothbrush" (RX J0603.3+ 4214), a cluster that contains one of the brightest radio relic sources known.

TL;DR: In this paper, a new calibration scheme, which is named facet calibration, was proposed to obtain deep high-resolution LOFAR High Band Antenna images using the Dutch part of the array.
