Apertif Time Domain FRB observation cone search (DR1)

This is the first release 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 Please note that the ARTS DR1 collection available from this end-point is superseded by the ARTS DR2 collection.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. The ARTS DR2 FRB observation cone search can be reached at https://vo.astron.nl/arts_dr2/q/obs_cone/form.
