(a) The direction and (b) magnitude of wave vectors (k) determined by the J×B method as a function of frequency in the spacecraft frame in GSE coordinates. Data were averaged over all four MMS observatories. Here, k ≈ k⟘ ≫ k॥.k varies as ωsc and ωsc0.47±0.10 for fsc below and above 4 Hz, respectively.
