Estimation of ejecta masses for targets composed of 0.25 (full red line, Brisset et al. 2018), 1 (dashed black), and 13 mm grains (full black line). We also show the mass estimations for mixed targets (green line). As described in the text, ejecta production was characterized as follows: (0) no ejecta; (1) the ejected mass is much lower than the projectile mass; (2) the ejected mass is to the order of the projectile mass; (3) the ejected mass is much higher than the projectile mass. For fine grains and mixed targets, only lower ejecta masses were observed. The impact velocity given for each target type is the average of all impacts that created the same amount of ejecta. The horizontal dotted line marks the limit between the ejection of individual particles and an ejecta blanket.
