Notes.

(a)

Number of events listed in our sample for each individual repeater.

(b)

Maximum value of the radio flux density at peak time for a given FRB.

(c)

Maximum value of the radio luminosity for a given FRB.

(d)

Test statistic.

(e)

ULs at a 95% confidence level on the gamma-ray flux in units of 10−10 ph cm−2 s−1.

(f)

ULs at a 95% confidence level on the energy flux in units of 10−13 erg cm−2 s−1.

(g)

ULs at a 95% confidence level on the luminosity in units of erg s−1.

(*)

The analysis of this repeater was limited between Jan 2016 and Aug 2021 (see Sect. 3.2).

(**)

FRBs with known host galaxy and therefore measured luminosity distance (DL).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
