[time-nuts] Interesting paper on GPSDO performance

While googling around during lunch today, I came across this interesting 
2005 paper from NIST by Michael Lombardi et al comparing the performance 
of four commercial GPSDO:

(that's a horrible URL -- this is easier: http://bit.ly/vv141K )

The paper doesn't identify the manufacturer or model of the four 
devices, but I'm pretty sure unit "A" is a Z3801A.  I haven't had a 
chance to compare specs to see if B, C, and D can be identified.
