Request: Planetary orbit periods, sidereal and tropical

Is anyone here able to confirm that the sidereal and tropical orbit
periods given at
http://nssdc.gsfc.nasa.gov/planetary...aturnfact.html and
http://nssdc.gsfc.nasa.gov/planetary...piterfact.html are in
accord with the best data currently available? A reference for the
confirmatory evidence would be appreciated. (The NASA data is from the
Astronomical Almanac, 2000.)

Best,
Stephen
