Path: Orbit/OrbitCoord
% Convert ECI to Sun Earth rotating coordinates about the barycenter.
The coordinate frame is +x pointing at the Earth along
the Sun-Earth line. +z normal to the Sun-Earth (ecliptic) plane
and +y completing the set.
Computes the plane by looking at the sun vector at jD(k) and then 1 day
later. By default, "SunV1" is used to get the sun vector. If a second
argument is entered, the JPL ephemerides are used.
Type ECIToSunEarthRot for a demo.
Since version 11.

Inputs
------
jD (1,:) Julian date (days)
JPL (1,1) Optional. Enter this input (any value) to use
the JPL ephemerides. Otherwise, SunV1 is used.
