Histograms of the count of cold electron detections by RPC-MIP (blue bars), the count of RPC-MIP electron density measurement (red bars) and the count of mutual impedance spectra acquired in phased SDL sub-mode (black bars) as a function of the cometocentric distance expressed in km. The cold-to-acquired ratio is shown as a line of yellow squares. The line of green squares shows the fraction of time where Rosetta was in the southern hemisphere. Each histogram ismade for a different range of heliocentric distances.
