Distribution of 1 /aori (top panel), 1 /afut (middle panels) and δ(1 /a) for considered LPCs. The black histogram given in the top panel represents the distribution taken from MW08. The uncertainties of our 1 /a-determinations were incorporated in these 1 /a-histograms by taking the full cloud of VCs for each comet. Two comets are outside the right border in the upper plot: C/1914 F1 (1 /aori = 600 ± 153, orbit of 2b class) and C/1937 N1 (1 /aori = 507 ± 101, 2a class), both with NG orbits.
