Correlation coefficients between simulation and the CRLB in a water-only signal over multiple echo-train lengths. The uncertainties in chemical shift and amplitude have a very high correlation with the CRLB, as does the uncertainty in $T_2^{*}$ at ETL=16. However, correlation between the uncertainties in $T_2^{*}$ and the CRLB decreases as the number of echoes decreases.

No. of Echoes	Chemical Shift	$T_2^{*}$	Amplitude

12	0.9996	0.9944	0.9999
