Figure 4
Curve fit of a single data set of gold nanoparticles of the NIST reference material RM-8011 (De Temmerman et al., 2014; Kaiser & Watters, 2007) using a model of spheres with Gaussian size distribution and the initial parameters shown in Fig. 2. The uncertainties of the measured intensity values are displayed as blue lines. The mean radius is X0 = 4.48 (5) nm and the width of the size distribution is s = 0.44 (5) nm. Right-hand figure: covariance matrix and confidence intervals of fit parameters to assess (inter-)correlation of parameters. |
