Top Left: Sketch of write line in purple, translated read line in red, and fit to read line above boundary layer in blue, y/δ = 1.0−1.6 ΔY1. Bottom Left: Sketch of read deviation from freestream fit in blue, and mean read deviation from freestream fit in gold. Top right: Visualization of ΔY1 and \(\overline{\Delta {Y}_{1}}\) of bottom left for all realizations in one shock tunnel run. Bottom Right: Visualization of ΔY2 and ΔY2RMS for all realizations in one shock tunnel run.
