Noise amplification in the MR-STAT experiment when all six parameters (T₁,T₂,|ρ|, ∠ρ, $\mid B_1^{+}\mid$, ω) are reconstructed. The numerical values inside the table refer to the log ₁₀ of the condition number of the covariance matrix C. Large values mean large noise amplification. The condition number is reported as a function of the experiment length (numbers of readout lines) and spatial resolution (grid sizes) for a small scale, homogeneous in-silico model. The number of samples per readout line is equal to the number of grid points along one dimension. An empty cell means that C is rank deficient (infinite condition number) and the problem can not be solved.
