DSA-110 Event Archive

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. This page summarizes high-quality, public data sets, including metadata for each event. A low-latency (60 second) alert system is also in development.

Event table

Click on the “DOI” link to view the candidate data, including a summary plot. A description of the data released at each DOI can be found in the data README. The search field will filter the table by running a 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. Full release is versioned 1.0. 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.
