Monte Carlo Simulation of qMT fitting results vs. SNR: (a) scheme (1) (black) with first-order approximations, (b) scheme (1) (red) with direct fitting, and (c) scheme (2) (blue) with direct fitting. True values are indicated by dot lines. Data points are slightly shifted to allow a clear comparison. Note that the previously employed first-order approximations in scheme (1) lead to systematic deviations from the input value, and that scheme (2) has significantly smaller kmf uncertainties than scheme (1), even when no first-order approximations are made.
