 $a$ is semimajor axis, $(h,k)=e~(\sin\varpi,\cos\varpi)$ where $e$ is the 
 eccentricity and $\varpi$ is the longitude of perihelion, $(p,q)=
 \tan(i/2)~(\sin\Omega,\cos\Omega)$ where $i$ is the inclination and $\Omega$
 is the longitude of node, and $\lambda=\varpi+M$ is the mean longitude in
 orbit ($M$ is the mean anomaly). Default reference system is that of mean ecliptic
 J2000. Orbital solution, together with formal standard deviation uncertainties, is from
 the AstDyS catalog as of May~2009 (e.g., Kne\v{z}evi\'c et~al. \cite{Kne2002}). The
 adopted absolute magnitude values $H$ are from MPC; in general, their uncertainty
 is $\pm$$0.5$~mag. Note the last member,
 2003~UD112, is a single-opposition asteroid with a very loosely determined orbit.
