352 fan-beams are searched for dispersed single pulses in real time, using a custom version of the heimdall software on 8 Nvidia GeForce GTX TITAN X (Maxwell) GPUs with a latency of 8-s. The resulting candidates were then processed offline, typically the following morning for overnight pulsar timing (RFI is much reduced at night, and the telescope is made available for maintenance on week days). On weekends, the telescope is usually operated continuously. The candidate processing pipeline used is described in detail in [@Caleb]. The process followed is:

1.  obtain 352 data streams (8-bits/sample), one for each fan-beam, at 655.36-$\upmu$s sampling

2.  search time series for single pulses with width, $0.65536 < W <
      41.943$ ms ($W = 2^\mathrm{N} \times 0.65536$ ms, where N = 0,1,2...) and DMs in the range $100 < \mathrm{DM} < 2000$ pc cm$^{-3}$,

3.  remove events occurring simultaneously in more than 3 fan-beams at a given instant in time,

4.  classify only events with S/N $\geq10$, DM $\geq100$ pc cm$^{-3}$ and $W\leq41.943$ ms as potential FRB candidates. These then require human scrutiny of the diagnostic plots, to remove candidates that were RFI, almost always due to narrow-band mobile handset emissions in our operating passband and
