CL_oe_kep2cirEqua

Description

• This function is deprecated.

  Replacement function: CL__oe_kep2cireq

  "cirEqua" orbital elements are identical to "cireq" orbital elements except that ix=2*sin(i/2)*cos(raan) and iy=2*sin(i/2)*sin(raan)

• Converts classical keplerian orbital elements to orbital elements adapted to near-circular near-equatorial orbits.

  The transformation jacobian is optionally computed.

  See Orbital elements for more details

Parameters

kep:
