Successful trials in detecting slopes. In the detection of the slope angle, detected data are averaged with 100 trials.

Real slope angle (deg.)	Successful detection rate	Mean value (deg.)	Max. value (deg.)	Min. value (deg.)	Variance (deg.)
−20.0	100/100	−20.0	−18.3	−24.1	0.926
−10.0	100/100	−12.7	−11.4	−14.0	0.261
10.0	100/100	10.3	10.9	9.52	0.0748
20.0	100/100	21.4	22.3	20.1	0.168
