Re: Update posted to Find_Orb

Hi
When I generate state vectors ephemeris (center Sun) I have different results in XV YV ZV vectors compare to results in elements.txt
Example (elements.txt)
Orbital elements: 2016 EZ26
Perihelion 2016 Apr 25.991590 +/- 0.0546 TT = 23:47:53 (JD 2457504.491590)
Epoch 2016 Mar 5.0 TT = JDT 2457452.5 Earth MOID: 0.0016 Ma: 0.0925
M 346.203985 +/- 0.39 Find_Orb
n 0.265350889 +/- 0.00728 Peri. 157.223541 +/- 0.36
a 2.398404060 +/- 0.0439 Node 66.985525 +/- 0.35
e 0.58865930 +/- 0.00738 Incl. 6.764901 +/- 0.053
P 3.71 H 22.6 G 0.15 U 9.4
q 0.986561204 +/- 0.000406 Q 3.810246916 +/- 0.0892
From 31 observations 2016 Mar. 1-5; mean residual 0".36
# State vector (heliocentric ecliptic J2000):
# -1.151924729028 0.275602741425 0.138548677285 AU
# 2.365142370263 -19.131109078500 -1.145464123342 mAU/day
And ephemeris results:
2457452.50000 1.000000 1
2457452.50000 -1.1519247290 0.1977490727 0.2367444008 0.0023651424 -0.0170968099 -0.0086608609
Created Sat Mar 05 18:59:05 2016
Ephemeris start: 5 Mar 2016 0:00:00
Ephemeris end: 6 Mar 2016 0:00:00
Times are all TDT
Positions/velocities are equatorial J2000, in AU and AU/day
-----
ups, now I see, in ephemeris is equatorial J2000 and elements.txt is ecliptic J2000
Can I change ephemeris or settings to output in ecliptic J2000 (to implement in Celestia soft).
