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 BN component of the magnetic field, labeled δBN1, as a function of time. (a) The points derived from a histogram of the success of 1 hr increments in the component BN of the magnetic field ﹩{\boldsymbol{B}}﹩ (δBN1). 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. R2 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 BT component of the magnetic field, δBT1.
