Time series of Encounter 4 turbulence properties: rms magnetic fluctuation δBrms, normalised rms fluctuation δB∕B0, magnetic compressibility CB, magnetic spectral index αB, cross helicityσc, residual energy σr, magnetic field angle to the radial θBR, Taylor hypothesis parameter ϵ, and predicted angular distance to the heliospheric current sheet ϕHCS. The red line is a ten-point running mean of αB. Values of ϵ for which the Bourouaine & Perez (2019) model is valid are marked with blue dots and points for which it is not valid are marked as red crosses. The vertical dashed lines indicate the intervals used to calculate the spectra in Fig. 6.
