Integrated sensitivity map of the Cassini Cosmic Dust Analyser, over the years 2004 until 2010. The crosses are simulations of dust impacts, colored according to impact year. The plot is drawn in the ecliptic frame and abberation due to spacecraft motion is taken into account. This “smears” out the directionality of the dust impacts over the instrument field of view. The upper plot shows the simulated impacts for dust with β = 1.1, Q/m = 0.59 C/kg, and the lower plot shows the simulated impacts for β = 1.5, Q/m = 1.5 C/kg. The whiter the background color, the longer Cassini CDA has been pointed towards that region of the sky.
