pylupnt.EphemerisFitOptions

class pylupnt.EphemerisFitOptions

Configuration for LansEphemeris.fit/eval.

property frame

Frame the input states and fitted output are represented in (e.g. MOON_CI, MOON_PA).

property gm

Central-body gravitational parameter [m^3/s^2].

property num_fourier_terms

Fourier terms (harmonics of the argument of latitude) added to the residual model; 0 = pure Chebyshev.

property poly_order

Chebyshev polynomial order for the position residual (velocity from its analytic derivative).

property use_keplerian_baseline

If true, subtract an osculating two-body Kepler baseline before the polynomial fit.
