Table 4

Results of Monte Carlo study of the estimated amplitudes (mean ± SD). The true values of NAA, Cr, and Ch are 48, 36, and 24, respectively; the CRLBs are 0.1574, 0.1288, and 0.1858 for Lorentzian, Gaussian, and Voigtian, respectively.

Lineshape	NAA	Cr	Ch
Lorentzian	47.99±0.27	35.99±0.31	24.02±0.30
Gaussian	48.00±0.18	36.00±0.19	24.00±0.19
Voigtian	48.00±0.37	36.00±0.40	24.00±0.38
