Bruce, Approximately what range of tau and ADEV(tau) would this VLBI requirement correspond to? A couple of the TBolts I've tested are at or just under 1e-12 at 1 second and stay almost flat out to 100 or even 1000 seconds. /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
