I want to determine the angle of a satellite’s ascending node with respect to the apparent Sun. I can get the TimeStampedPVCoordinates of the Sun in the TOD frame, and from there calculate the angle from ECI X-axis to the Sun. But I would like to know if the TimeStampedPVCoordinates are instantaneous values or if they consider light time travel (“apparent”). I can’t seem to find anything in the javadocs that would indicate one or the other.
Thanks,
Greg
