Relative errors for the different clock models under the (a) Dispersed I, (b) Dispersed II, (c) Aggregated I, and (d) Aggregated II calibration schemes. The whiskers represent the standard error of the relative rates. The exponential epoch model (TDRexp) is associated with the lowest mean relative error for all four calibration schemes.
