Resulting parameters from MCMC sampling to describe the unfiltered data (corresponding to the fundamental n = 1 mode) (left column), and to describe the filtered data (corresponding to the third harmonic n = 3) (right column). The parameters are amplitude (top), period (middle), and damping time (bottom). The black diamonds show the MAP parameter value from the MCMC sampling, and its credible interval is shaded light grey for each slit. The hashed regions correspond to slits where the data was not good enough to get reliable time series, predominantly caused by an overlapping loop. The blue region denotes the approximate node for the third harmonic, where amplitude is small and data is not to be trusted.
