Caption: Figure B1.

The formed-beam response of the detection beam (green circle) for the brightest detected pulse from PSR J2108+5055. The cyan circles are the CHIME/FRB formed beams, and the star marks the position of PSR J2108+5055. Unfortunately, for this pulse, data were saved only for a suboptimal beam, resulting in a noisier calibration, as is apparent in the left panel of Figure 3. The axis labels denote degrees from zenith in the east–west and north–south directions.
