Table 1.

Original and optimal schemes with roughly the same total acquisition time

1) Original Scheme(10): V = 3.14 × 104 s, Vmax = 7.82 × 105 s, Time cost= 105.54 s.	2) Optimized for a typical parameter set: V = 1.39 × 104 s, Vmax = 3.35 × 105 s, Time cost = 105.55 s.	3) Optimized for parameter ranges: V = 1.51 × 104 s, Vmax = 3.25 × 105 s, Time cost= 103.25s.
