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.
