The average grain size, the integrated mass of each tail, and the radius of an equal-mass sphere. Each graph contains the following information: (1) the average grain size along the radial distance of the tail from the nucleus (black line); (2) the total mass of dust obtained by integrating the mass of particles along the radial distance of the tail from the nucleus (green line); and (3) the radius of an equal-mass sphere, where the mass is obtained by integrating the mass of particles along the radial distance of the tail from the nucleus (blue line).
