Data for: Nonparametric Bayesian inference for the spectral density based on irregularly spaced data

The vertical acceleration (VAC) is an important proxy of the vertical vibration of the hull. Two VAC series (unit: m/s^2) from two measurement points along the hull girder are given. Each data series consists of 1696 observations over 1 hour (3,600 seconds). They are irregularly spaced. See the article for more detailed description.

垂向加速度（Vertical Acceleration，VAC）是表征船体垂向振动的重要代理参数。本数据集包含沿船体梁布置的两个测点的VAC序列，单位为米每二次方秒（m/s²）。每个序列包含1696个观测值，采样时长为1小时（即3600秒），且观测值的时间间隔并非均匀分布。更多详细说明请参阅相关研究论文。
