Distributions of geocentric and orbital parameters of all 923 meteor showers from the MDC: the averaged values of the geocentric velocities (V_G), the geocentric right ascension (α) and declination (δ) of the shower radiants, the sun-centred ecliptic longitudes (λ_G – λ_S) and ecliptic latitudes (β_G) of the shower radiants, the perihelion distance (q), eccentricity (e), argument of perihelion (ω) and the longitude of the ascending node (Ω), and inclination of the orbital plane (i).
