Information on resource 'Apertif Time Domain Data Release'
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from this end-point is superseded by the ARTS DR2 collection.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.
