Table 3.
The effect of elevation and roll on the number of pegs reached and the (MB, MD) → (x, y) mapping uniqueness and resolution.

|---|---|---|---|---|---|---|
| N pegs | % unique | AMD | N pegs | % unique | AMD | |
| Realistic kinematics, including roll and elevation | 1048 | 98.79% | 1 | 55 | 100.00% | 1 |
| No elevation | 633 | 96.28% | 0.691 | 67 | 100.00% | 0.940 |

N pegs: number of pegs; % unique: percent of the (MB,MD) space that uniquely maps to an (x, y) peg location; AMD: average minimum distance computed over the entire mapping. The AMD has been normalized to equal exactly 1 for normal whisking kinematics so that the effects of altered kinematics can be quantified.
