The DSA-110 is a radio
interferometer designed to discover and localize Fast Radio
Bursts. The project releases data publicly to support follow-up
observations and analysis. This archive is the gateway to public DSA-110
data. A low-latency alert system is separately available via the VOEvent
standard.
Event table
The “DOI” link will go to a page with public data for the FRB. A
description of the data released at each DOI can be found in the data README. Use the search field to filter the
table by string query on all fields. A list of official names for
DSA-110 FRBs can also be found on the Transient
Name Server.
Column names:
- Internal Name – Unique internal name generated by the real-time
search system. Names begin with an MJD date in format with a
suffix that iterates through four lowercase letters (starting at
“aaaa”).
- MJD – Modified Julian Date of event (defined in local (topocentric)
frame at top of band, 1530 MHz).
- DM – Dispersion Measure identified by real-time system in
pc/cm3.
- Width – Duration of event (after dedispersion) that produces maximum
SNR in real-time search system in milliseconds.
- SNR – Signal-to-noise-ratio of event measured in a single power beam
as a function of time (using Heimdall search code)
- RA – Right Ascencion (J2000) of peak of localization probability
distribution in degrees.
- Dec – Declination (J2000) of peak of localization probability
distribution in degrees.
- PosErr – Error full-width at half-max of the localization region in
units of arcseconds (largest of two axes). The 90% error ellipse is 2.15
times larger than the value quoted here.
- Notes – Human annotations describing the purpose of data set or
associations, if known. Examples include: test, pulsar, or a name of a
known source.
- Version – Release version of data. Ad hoc releases are <1.0.
Version >=2.0 include filterbank files. Minor increments do not
affect science interpretation, but major increments do.
- DOI – Unique, persistent URL to public data set, which includes
event localization region and dynamic spectrum. Data and DOI are managed
by CaltechDATA.
- Publication – A link to the ADS entry for the first refereed
publication that includes the FRB.
