Notes. If the value of 112° for the ascending node (from Jenniskens et al. 2016) is used instead of the mean value (118°), then the resulting DSH is 0.16. Orbital elements (mean values for shower data): q = perihelion distance, e = eccentricity, i = inclination, Node = node, ω = argument of perihelion, DSH = Southworth and Hawking D-criterion with respect to 2001 W2 Batters.
