Pixel‐by‐pixel scatter plots of several methods’ (LMSAL’s LCT, FLCT, and DAVE; top to bottom) estimates of the flux transport rate, ﹩\boldsymbol{u}B_{z}﹩, defined in eq. (3), with ANMHD’s flux transport rate, ﹩\boldsymbol{U}B_{z}﹩, over the shortest time interval between data dumps, ﹩\Delta t=250﹩ s. Blue and red are used to distinguish x‐ and y‐components, respectively. For each method, nonparametric Spearman rank‐order correlation coefficients and linear (Pearson) correlation coefficients are shown for both components of the flux transport velocity.
