VizieR Online Data Catalog: NGC 3184, 4736, 5055 and 5194 LOFAR & WSRT maps (Heesen+, 2019)

We present maps of four nearby galaxies obtained with the Low-frequency ARray (LOFAR) using the high band antennae (HBA). The maps were produced with the facet calibration technique, ensuring direction-dependent calibration, using the FACTOR pipeline. These maps were imaged and deconvolved with the Common Astronomy Software Applications using the multi-frequency-multi-scale CLEAN algorithm. Finally, the maps were convolved in the Astronomical Image Processing System (AIPS) to a circular synthesised beam. In order to measure flux densities, we integrated in ellipses encompassing the 3-sigma contour line. In addition, we present maps and flux densities at the same angular resolution from archival observations with the Westerbork Synthesis Radio Telescope (WSRT).
