v0.7.0-rc.2

v0.7.0-rc.2 — release candidate

Uncertainty-first orbit propagation, ephemeris, orbit determination, and
close-approach / impact analysis for asteroids and comets, powered by
automatic differentiation. Distributed as a Rust wrapper, C ABI, Python
package, and command-line tool over a consistent API.

Propagation & uncertainty

• N-body propagation with non-gravitational forces.
• GR15 and DOP853 integrators.
• Linear, second-order, and adaptive uncertainty mapping via automatic
  differentiation.

Orbit determination

• Initial orbit determination through N-body differential correction with
  outlier rejection.
• Optical and radar astrometry; non-gravitational parameter recovery.
• Fitted orbits carry state, covariance, and non-gravitational parameters
  for direct re-use in propagation and further fitting.

Close approaches & impact

• Close-approach detection, B-plane geometry, and impact-probability
  estimation across multiple uncertainty methods.
• Per-epoch tagged covariances.

Ephemeris

• Observer ephemeris generation with sky-plane uncertainties.

Every published quantity carries its uncertainty.
