Fig 1.
Averaged error rate as a function of degrees of assistant referees’ visual angle between the passer and the defender.
Note that the number of observations contributing to each bar varies.
Fig 2.
Averaged error rate as a function of the separation in depth between the assistant referee and the passer in meters.
Note that the number of observations contributing to each bar varies.
Fig 3.
Averaged error rate as a function of the separation in depth between the assistant referee and the defender in meters.
Note that the number of observations contributing to each bar varies.

Fig 5.
All offside calls made by the ten assistant referees who participated in the laboratory-based attentional spread task plotted as a deviation from each assistant referee’s maximum visual angle.
The error rate for the assistant referees’ decision requiring visual angles less than the assistant referees’ individual maximum visual angle measured in the laboratory task is presented in gray and for situations requiring visual angles greater than the individual maximum visual angle in black. The X-axis shows each assistant referee’s number and the Y-axis shows the assistant referees’ error rate.
