  1. The vibration mode numbers are indicated by m, where frequencies are sorted in ascending order. MPMFs (estimates) and true frequency values are in Hertz with corresponding errors (%) in parentheses. Cumulative distribution function (CDF) values indicate the significance of each peak in the overall probability density function (PDF).
