Influence of resistivity anisotropy on diffusion correction in (a) sample 1 and (b) sample 2 of ${\mathrm{ZrAs}}_{1.58}{\mathrm{Se}}_{0.39}$ for $F=0$ and $D_{cE}$ obtained from the Einstein relation (solid lines). Fits including diffusion and Cooper channel contribution (dashed lines) ($D_c^{\#1}=2.1\pm 1.1{\mathrm{cm}}^2/\mathrm{s}$, $D_c^{\#2}=0.33\pm 0.17{\mathrm{cm}}^2/\mathrm{s}$ and $D_c^{\#1}=13\pm 6{\mathrm{cm}}^2/\mathrm{s}$, $D_c^{\#2}=2.1\pm 0.9{\mathrm{cm}}^2/\mathrm{s}$ for ${\rho }_a^{\#3}$ and ${\rho }_a^{\#4}$, respectively). Calculated MR at 14 T due to interaction in the Cooper channel when the Zeeman effect is included [2] (dotted lines).
