Parameters for the fits to the log 
full sample distribution using different numbers of Gaussians.
| Parameter | Value | |||
|---|---|---|---|---|
| Model | G2 | G3 | G4 | G5 |
| Nfree | 29 | 26 | 23 | 20 |
| χ2 | 70.6 | 48.0 | 29.8 | 35.8 |
 |
2.61 | 2.00 | 1.42 | 1.99 |
| BIC | 91.6 | 79.5 | 71.7 | 88.2 |
Notes. G2−5 refer to the models using 2−5 Gaussians. Nfree is the number of free parameters, χ2 and 
the chi-squared and reduced chi-squared statistics, respectively, and BIC is the BIC value calculated using BIC = χ2 + klog(N), where k is the number of fitted parameters and N the total number of bins in the histogram.
