Icy particles analysed were measured between 2014-11-01 and 2015-02-28, at a nominal NG signal less than 5.0 × 10⁷ cm⁻³, an off-nadir angle lower than 9°, and a phase angle in the range between 86.3° and 97.8°. On the x-axis, the central values of bins with a width of 0.04 au are shown. Panel a: number of icy particle detections as a function of the heliocentric distance. Panel b: NG detection rate as a function of heliocentric distance. Panel c: NG detection rate, multiplied by the square of the average cometocentric distance, as a function of the heliocentric distance.
