Context. The electrostatic potential of a spacecraft, V S , is important for the capabilities of in situ plasma measurements. Rosetta has been found to be negatively charged during most of the comet mission and even more so in denser plasmas. Aims. Our goal is to investigate how the negative V S correlates with electron density and temperature...

We study the evolution of a cometary ionosphere, using approximately two years of plasma measurements by the Mutual Impedance Probe on board the Rosetta spacecraft monitoring comet 67P/Churyumov-Gerasimenko (67P) during August 2014-September 2016. The in situ plasma density measurements are utilized to estimate the altitude-integrated electron...

The WHISPER (Waves of HIgh frequency and Sounder for Probing Electron density by Relaxation) instrument has been monitoring the bulk properties of the plasma environment around Earth for more than twenty years. Onboard the 3‐D Earth magnetospheric CLUSTER‐II mission, this experiment delivers active and natural electric field spectra, in a...

Purpose of the Report. Statistical Parametric Mapping (SPM) is widely used for the quantitative analysis of brain images from F-18 fluorodeoxyglucose Positron Emission Tomography (FDG-PET). SPM requires an initial step of spatial normalization to align all images to a standard anatomical model (the template), but this may lead to image...
