Information on resource 'Apertif Time Domain Data Release'
This is the 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.
Services defined within this resource descriptor
- Apertif Time Domain FRB detection cone search
This service provides a cone search on the table of FRB detection,
and returns links to the FRB properties as well as one to the PSRFITS
files with the data.
- Apertif Time Domain FRB observation cone search
This service provies a cone search on the table containing metadata
from the data obtained throughout all observations performed for the
survey. If an FRB was detected, a link to the FRB properties as well
as one to the PSRFITS data are provided. If no FRB was deteced in the
data, a link is provided to a service that lists all information
needed to request the raw data to be staged from tape to disk, as well
as documentation on the procedure to perform this request. Please note
that requests for raw data are handled on base of best effort.
