Observations of intermittency using hourly average data by Voyager 1 from 2013.3593 to 2014.6373. Panel (b) shows the time series of 1 hr increments in the B _N component of the magnetic field, labeled δB _N1, as a function of time. (a) The points derived from a histogram of the success of 1 hr increments in the component B _N of the magnetic field ﹩{\boldsymbol{B}}﹩ (δB _N1). The solid curve is a fit of a q-Gaussian distribution to the observations. The value of q, a measure of the intermittency of the fluctuations, is shown in the upper right corner of the panel together with the amplitude A and the parameter β that is inversely related to the width of the distribution. R ² is the coefficient of determination of the fit. The panels on the right, (c) and (d), correspond to the panels on the left except that they refer to the 1 hr increments in the B _T component of the magnetic field, δB _T1.
