Compression residuals coherence for raw real, calibrated real, and calibrated simulated data. For each panel in the top row, the coherence is computed using two compressed minus uncompressed data residuals from two separate datasets. To eliminate solver noise, the calibration gains solution from each uncompressed dataset is applied to its compressed version before obtaining the residuals. The average coherence for each top row panel is shown in the bottom row as a function of both k_⊥ (left) and k_∥ (right) modes.
