method uses its own shower assignment algorithm, we have demonstrated (@veres10) that its results are consistent with the widely-used Southworth-Hawkins D-criterion $D_{SH}$ (@south63) for meteor stream identification. In accordance with several restriction criteria developed in our previous work (@veres10), we selected a high quality subset of orbits for further analysis. The criteria fulfilled $111$ of $250$ December Monocerotids and $110$ of $333$ November Orionids detected in the years 2007-2009.

Of 111 MON meteors, only 8 have hyperbolic orbits and among 110 NOO meteors, 14 have semimajor axes larger than 100AU or eccentricity higher than $1.0$. We also employed $D_{SH}$ to distinguish possible rogue sporadic meteors among MON and NOO assigned to the showers by SonotaCo. In comparison with the nominal orbit of the comet C/1917 F1 Mellish, all MON and NOO meteors fall within $D_{SH}<0.4$. Even within stricter $D_{SH}<0.15$, 105 MON and 97 NOO are found (according to SonotaCo shower assignment). Independently, we selected the MON and NOO shower members by using the iteration procedure according to @por94. In the iteration for the $D_{SH}$=0.15, 105 MON and 97 NOO were identified. This result is almost identical to SonotaCo assignment of both shower members. The showers appear very narrow in the
