Extended Data Fig. 6: Relative Root Mean Squared Error in the angular fit with large V1.

(a) The angular dependence of nonreciprocity measured at ν = 1.2. (b) Relative root-mean-squared error (RRMSE), defined according to Eq. M2, as a function of V1 (left panel), V3 (middle panel), and β (right panel). (c) The angular dependence of nonreciprocity measured at ν = 2.0. (d) Relative root-mean-squared error (RRMSE), defined according to Eq. M2, as a function of V1 (left panel), V3 (middle panel), and β (right panel).
