Mean orbital elements (all analytical models)
mean_oe = CL_ex_meanElem(mod, type_oe, osc_oe [, er, mu, j1jn])
Computes mean orbital elements from osculating orbital elements.
This function is a wrap-up for all available analytical models.
The available models are:
"central": Central force (osculating elements = mean elements)
"j2sec": Secular effects of J2 (osculating elements = mean elements by convention)
"lydsec": Lyddane (mean elements include secular effects only)
"lydlp": Lyddane (mean elements include secular and long period effects)
"eckhech": Eckstein-Hechler (mean elements include secular and long period effects)
Notes:
- There can be 1 or N initial times, and 1 or N final times.
- Conversions take place if the type of orbital elements is not the "natural" type for the model.
See Propagation models for more details.
