(a) Internal tail-core RDFs of the rNCP, aNCP, and paNCP in the presence of K⁺ and Mg²⁺ salts for the systems with 10 NCPs in the simulation cell. (b) Dependence of the intensity of the first maximum of the internal tail-core RDF on salt concentration (KCl or MgCl₂) for a system with a single NCP particle in the simulation cell. The maxima in the 10-NCP system (a) are labeled in b with solid symbols of the same shape as the corresponding systems in the single-particle systems (b). The single red square with a cross and blue triangle with a cross represent data at zero percent Mg²⁺ in the systems represented in Fig. 5.
