“Both” indicates both ChB and SbS. F, the average fraction of RYRs in the specific configuration determined by Asghari et al. (2014) for 0.1, 1.0, and 4.0 mmol/l Mg²⁺ (patterns A, B, and C, respectively); Isl, isolated RYR configuration; N, the number of RYRs in each specific configuration and pattern, calculated from the given N_RYR and the average fraction F.
