FRB 191108 (DR1.2)

Data accompanying A bright, high rotation-measure FRB that skewers the M33 halo by Liam Connor and team (ADS | arXiv PDF).

Raw time-frequency data in standard FITS format is
available for the combined Synthesized Beam 37, and the 12 individual Tied Array Beams (6 GB total).
The FRB is visible 1.7s into the 7s file.

A polarisation-calibrated numpy array of a zoomed-in part of the same synthesis beam data is available as a 50 MB binary .npy file.

The direction-dependently calibrated mosaic image of the field is available as a 100 MB FITS file.
