Notes.

^(a)

Time since FRB expected arrival time referenced to infinite frequency (i.e. the time delay due to dispersion is removed).

^(b)

Timescale of the peak candidate as evaluated with MEPSA.

^(c)

Background-subtracted count rate in the total HE pass band (which depends on the operation mode).

^(d)

Signal-to-noise ratio.
