Table A.2.

Summary of the results of the systematic search for γ-ray counterparts performed over a set of five different integration times through two different search methods: the multi-detector and the summed-detector searches (Sect. 3), applied to both the whole sample of FRBs and some of its sub-classes.

Class/search method Δ t = 100 μs Δ t = 1 ms Δ t = 10 ms Δ t = 64 ms Δ t = 1.024 s
Individual FRB:
 – Multi-detector search (a) 20 (23) 17 (27) 8 (14) 14 (9) 7 (4)
 – Summed-detector search (SDS) (b) 59 (45) 44 (38) 35 (26) 13 (12) 3 (2.3)
Cumulative LC: all (SDS) (c) 1 (0.4) 1 (0.6) 0 (0.56) 0 (0.30) 0 (0.06)
Cumulative LC: Rep/Non Rep (SDS) (d):
 – Non Repetitive (33) 1 (0.4) 1 (0.6) 0 (0.56) 0 (0.30) 0 (0.06)
 – Repetitive (6) 1 (0.9) 0 (0.7) 0 (0.58) 0 (0.30) 1 (0.06)
Cumulative LC: operation mode (SDS) (d):
 – Normal (30) 0 (0.4) 2 (0.6) 1 (0.56) 0 (0.30) 0 (0.06)
 – GRB (9) 3 (0.66) 1 (0.7) 2 (0.58) 0 (0.30) 1 (0.06)

Notes. For each pair of class/method and integration time, the number of candidates along with the expected number of false positives is reported in parentheses.

(a)

Trigger condition: simultaneous trigger for n ≥ 3 out of the 18 HE detectors for any given FRB.

(b)

Light curve obtained by summing the individual light curves of all 18 detectors for any given FRB.

(c)

Light curve obtained by summing all the total light curves of all 39 FRBs.

(d)

Number of FRBs per class is reported in parentheses.
