We use both Fourier and χ2 methods. The first column is the number of reference stars in the sample analyzed. The second column is the misalignment error c in Babylonian degrees. The third column is the measurement errors s in Babylonian degrees. The fourth column is the estimated epoch of observation tr with its uncertainty, or the standard deviation of the mean Δt. The fifth to seventh columns represent the uncertainties estimated by bootstrap resamplings.
