^aR_merge = Σ_h Σ_i|I_i(h) − 〈I(h)〉|/Σ_h Σ_i I_i(h), where I_i(h) is the ith measurement of reflection h, and 〈I(h)〉 is the weighted mean of all measurements of h.

^br = Σ_h|F_obs(h)| − |F_calc(h)‖/Σ_h|F_obs(h)|. R_cryst and R_free were calculated using the working and test reflection sets, respectively.
