Distribution of the ratio ${\Omega }_{\text{p}}^{\text{TW}}/{\Omega }_{\text{p}}^{\text{DSS}}$ (blue histogram) for the weak (left panel) and strong bars (central panel) as well as for both of them (right panel). Each panel reports the mean value (dashed vertical line), of this ratio with its corresponding error, calculated as the standard deviation around the mean, ɀ is the redshift, a is the spatial sampling, and Ν is the number of the galaxies. The blue curves in each panel represent continuous probability density functions derived from the data.
