Figure 7.

Sample containing the NO–Gd and the Gd–Gd rulers mixed in a $\mathrm{1}:\mathrm{2}$ molar ratio. The legend is the same as in Fig. . The NONO DEER channel contains a NO–Gd crosstalk signal ( $X_{\mathrm{1}}$ ), and the NOGd channel contains a Gd–Gd crosstalk signal in presence of a NO–Gd distance designated as  $X_{\mathrm{3}}$ . A comparison of how different neural networks fit this crosstalk signal is shown in Fig. S9b (part B).
