In Page 270, Chapter 18, Section 18.4.1, the sentence in lines 7ȓ10 should read as “Electronmeasurements can be affected by photoelectrons (see [Chapters 8 and 19]) and in certain low temperature plasma environments are limited by the finite energy bandwidth of the instrument”.

In Page 271, Chapter 18, Section 18.4.2, the sentence in lines 7–9 should read as “As detailed in Fazakerley et al. [Chapter 19], the post-launch calibration has been enhanced by the comparison with other experiments estimating the electron density in an independent way”.

In Page 275, Chapter 18, Section 18.4.3, the sentence in lines 12–13 from bottom of the page should read as “Unfortunately, a quantitative estimation of the Debye length limit has not yet been estimated for theWHISPER instrument [Chapter 12]”.

In Page 290, Chapter 19, below Figure 19.4, the sentence in lines 4–7 should read as “There are a greater number of data points for spacecraft C2 due to the greater availability of 3DR data from that spacecraft, as discussed in a companion paper in this volume [Chapter 8]”.
