while taking a break from the 86K EarthNight 32 bit data
NAIF updated a few things , mostly Pluto,Neptune,Uranus ,Saturn and the default naif kernel used "de721_full.bsp" for the planets
de721_full.bsp( 148.865 MB ) -- 1599 SEP 04 00:00:00.000 3000 MAR 03 00:00:00.000
or the 3.2 GIG "de431_full.bsp"
de431.bsp ( 3,230.288 MB)------ 13201 B.C. MAY 06 00:00:00.000 17191 MAR 15 00:00:00.000

it might be a good idea to have a thread on
---- the 8 planets and their moons , with the minor planet "pluto" and it's menagerie of bodies in SPICE kernels ---
I am no expert but between all of us here a consensus "should" be able to be found
I have been using an edited version of the old "Barycenters.ssc" based layout by :"volcanopele"
so if there are no objections to this starting point
the beginning of this talk will be with just the Barycenter file
if we all agree that this is a good start then how about making a pined thread on just the settings only
--- updated for the smaller 148 meg kernel ( 3.2 Gig is big ,for the de431.bsp )
My version of the Barycenters.ssc ( Linux read order issues and bug require this to be named "1.Barycenters.ssc" )
