Fig. 6

The horizontal axis corresponds to the perpendicular wavelength derived from the particle-sounding technique, whereas the vertical axis represents proton gyro-radius evaluated at local proton perpendicular thermal energy \({T}_{\perp }\) (taken from the MMS/FPI/DIS-MOMS dataset). The dashed line shows a linear regression of the data, with the results denoted in the figure.
