Distribution of ﹩\mathrm{log}\,\sigma {S}_{L}﹩ and ﹩\mathrm{log}\,(\sigma {S}_{L}/{S}_{L})﹩ versus the number of observations. The top panel presents the histogram of observation counts, while the right panels display the corresponding distributions of ﹩\mathrm{log}\,\sigma {S}_{L}﹩ (top right) and ﹩\mathrm{log}\,(\sigma {S}_{L}/{S}_{L})﹩ (bottom right).
