Results of a grid-search method for the determination of the natural frequency f and damping constant h of a Hi-net sensor. a Values of rr as a function of f and h.
b–e Observed (black line) and calculated instrument responses for various parameter sets: (b) f = 1.11 Hz and h = 0.68, c
f = 1.05 Hz and h = 0.55, d
f = 1.25 Hz and h = 0.80, and e
f = 1.0 Hz and h = 0.70. Each calculated waveform is colored according to the value of rr
