Figure 4. RMSD errors by optimizing the X-EISD score with a single experimental data type for $R_2$-dynamic ensembles derived from (a) ENSEMBLE, (b) RANDOM, and (c) MIXED pools.

The values are averages over 1000 ensembles of 100 structures each, and the numbers in parenthesis are standard deviations. The last row refers to the unoptimized ${\text{R}}_2$-dynamic pool of structures. Units are different for each experimental data type and are found in Table 1.
