Doublets etc...

Newbie to Celestia
Not bitchin?€™, just looking for help.
Since most stars are doubles or more in the universe... Several problems
1) Many stars listed as single ones on Celestia are actually doublets, triplets, and so on. Is there a fix for this somewhere?
eg. [[Castor is a complex sextuplet of stars.
Overall revolution between the 2 blue A-Bpairs is >450 years, ~467 years
1st [A] doublet is 9.2 days
2nd [B] is 2.9 days
The red doublet [C] has a 0.8 days period
Red C to the A-Bquadruplet period is ~10,ooo year
ecc .33 to A-B .36 on AB-C
Red pair is RETROGRADE to motion of the other 2 pairs !
REM: the C orbit about A&B is highly lopsided, elliptical, eccentric [almost hyperbolic].. So would look from ooh 6 suns in sky to "those are ours?" ..]]
2) Most of those faux "single" stars are color-coded with the "average" of colors, when in actuality the colors are quite different.
3) Quite oblate or prelate stars still shown as quite spherical.
4) Also shares a lot the common online goofs of things like Erkab and Arkab being the same?€¦ a drawback to all online info since most sites copy from sites not from real publications or people who know. In general online intel of stars is bad enough that no alien would find his way home if tried to steer by. At least you guys get HD and M coord corrections done well.
We are downloading from friend's computers and local library due to constraints put on us by the cleanup of Hurricane Katrina in our area and dialup.
Please email the responses/links to gelf@rocketmail.com
Thank you
p.s. are any of flares stars or variables shown as such?
