ALERT, the Apertif Lofar Exploration of the Radio Transient Sky, will investigate the Northern Sky with unprecedented speed and precision, to determine the nature of some of the most powerful flashes and explosions in the Universe.

FRB 121102 (DR 1.1)


This data release accompanies Repeating fast radio bursts with WSRT/Apertif by Leon Oostrum and team (ADS | arXiv PDF).
It covers raw data and higher-level products.

The raw data include psrchive files and high-resolution images for all (R1) bursts presented in the paper.
The data are available as a 900 MB tar file.

Higher-level data products

The higher-level data include the measured barycentric arrival times; dispersions measures (both S/N-optimised and structure-optimised DM, where available); width; fluence and wait times.
