Notes. The columns denote the population model, as mentioned in the text, the number of LOFAR sub-stations used, the number of beams per observation, the predicted rate per sky per day for the minimum fluence, the DM range searched, the spectral index of the FRB, the required observing time per event, the given rate and the sky coverage for this setup, the minimum fluence for the given setup, and the section and the figure this model and setup refers to. The modes stand for Incoherent Stokes (IS), Coherent Stokes (CS), Fly’s Eye (FE) and a Transient buffer board only mode (TBB), as explained in the corresponding sections. (a) Events per Gpc3 per day.
