Latitudinal and Local Time Variation of Ionospheric Turbulence Parameters during the Conjugate Point Equatorial Experiment in Brazil

Figure 5

Histogram of the χ 2 values from the least-squares fits of the model intensity PSD to the measured intensity PSD, for all applications of the IPE technique presented in this paper (from all three stations combined). A threshold of χ 2 = 0.5 (shown as the dotted vertical line) was chosen to identify good and bad fits between the model and the measurements.
