Dependence of \(N_{cnt} \left( {r_{bb} } \right)\) on \(r_{bb}\) and its standard deviation (error bars). Lower limits of some error bars are smaller than 0 on the x-axis because the standard deviation was calculated using the usual form: \(\left[ {N_{cnt} \left( {r_{bb} } \right)^{2} - N_{cnt} \left( {r_{bb} } \right)^{2} } \right]^{1/2}\).
