2018 BM33 and (206673) = 2003 YC111

Covariance clone convergence summary: - Objective: minimize nominal velocity

Prefix: 2018_BM33_2003_YC111_nominal_100

Run setup:

- Pair mode, 100 covariance clones per target plus nominal.

- 101 samples per target, 10,201 sample cross-combinations.

- Analysis epoch: JD 2461200.5.

- Objective: minimize nominal velocity.

- Nominal sample source: covariance.

- Integrator: REBOUND IAS15 in AU-yr-Msun, initial dt 0.3652564 day (0.001 yr), default IAS15 epsilon.

- Massive bodies: Sun; Mercury, Venus, Earth-Moon, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto barycenters; Ceres, Pallas, and Vesta.

- Test particles: all nominal/covariance-clone samples for the 2 targets; clones are massless and do not perturb the massive bodies or each other.
