Please see Section 6.3.2 Keplerian Orbit of the Thermal Desktop manual for a definition of the orbital elements. A Keplerian orbit uses the RA Sun to determine the position within the central body's year (orbit about the Sun).
Let me know if you found this helpful or have other questions or concerns.
Kind regards,
Doug
