test_orbElemOffset.test_orbElemOffset(useMeanAnomalyOffset)

Functional test for OrbElemOffset:

• When useMeanAnomalyOffset is False:

  All ClassicElements fields are summed element-wise:

  out = main + offset

• When useMeanAnomalyOffset is True:

  All fields except f are still summed element-wise. The f field is computed by interpreting offset.f as a mean anomaly increment DeltaM (rad) and performing

  E_main = f2E(main.f, main.e) M_main = E2M(E_main, main.e) e_out = main.e + offset.e M_out = M_main + offset.f f_out = E2f(M2E(M_out, e_out), e_out)
