This is the second time I've experimented with the "OrbiTrack" (Macintosh, from
ftp://ftp.physics.ox.ac.uk/pub/sat/programs/mac/) "Sat-to-Sat" option. Using
the oig elements below:

I'm not familiar with COLA, is that an IBM PC code? Are you "Mac challenged"?!
;) Hope this helps, and that it's correct (get a second opinion before you
book a flight)!

....
I would like to be able to table or graph the distance between
the two Cosmos rockets on an hourly basis for the time period 06/21
04:00 UT thru 04:00 UT on 06/24. What's the best way to do this?
Any software out there that will give me most of the info I need?
Or...can someone do this for me? ;)
As always, clear skies....Bill
