Notes.

^(a)

Time of arrival corrected to infinite frequency at the solar system barycenter.

^(b)

Fluence averaged over the observing bandwidth.

^(c)

Effective observing bandwidth used to calculate the average fluence, excluding flagged channels.

^(d)

Radio burst fluence, ℱ_R (i.e., Fluence × Bandwidth).

^(e)

Redshift-corrected intrinsic total radio burst release energy.

^(f)

X-ray burst fluence, ℱ_X (0.2−12 keV, corrected for Galactic absorption), 3 σ upper limit, assuming a cutoff power law spectrum as was observed for SGR 1935+2154 (Li et al. 2021).

^(g)

3σ upper limit to the X-ray (0.2−12 keV) to radio fluence ratio (η_x/r = ℱ_X/ℱ_R).
