vo@astron.nlsky-surveysfast-radio-bursts This is the first release (DR1) of data from the Apertif Radio Transient System (ARTS), a supercomputing radio-telescope instrument that performs real-time FRB detection and localisation on the Westerbork Synthesis Radio Telescope (WSRT) interferometer. It reaches coherent-addition sensitivity over the entire field of the view of the primary- dish beam. After commissioning results verified the system performed as planned, we initiated the Apertif FRB survey (ALERT). Over the first 5 weeks we observed at design sensitivity in 2019, we detected 5 new FRBs, and interferometrically localised each of these to 0.4−10 sq. arcmin. All detections are broad band and very narrow, of order 1 ms duration, and unscattered. Dispersion measures are generally high. Please note that the ARTS DR1 collection available from this end-point is superseded by the ARTS DR2 collection. DR2 includes all data from the DR1 collection that can be queried here.2023A&A...672A.117Vhttps://vo.astron.nl/tableinfo/arts_dr1.frb_obsSurveyResearchWSRTARTSRadioarts_dr1 This is the first release (DR1) of data from the Apertif Radio Transient System (ARTS), a supercomputing radio-telescope instrument that performs real-time FRB detection and localisation on the Westerbork Synthesis Radio Telescope (WSRT) interferometer.
