  1. The first column of the table contains a fork label, while the second column lists the vacuum frequency of the fork. The third, fourth and fifth columns show the geometric dimensions of the fork, length L, width W and thickness T, respectively. The experimental fork constant is presented in the sixth column. The last three columns of the table show the resulting fitting parameters \(\beta \), B and C, which assume the presence of the hydrodynamic drag only. The two \(W=75\mu \)m quartz tuning forks were previously reported[10]
