I haven't done any probing or changing of commands, so these comments 
are based on passive observation of monitor points and logs.

--------------------------------------------------------------------

GPS

No alerts to indicate loss of sync or timing quality

L356

Maser looks normal.  Drifting approximately 29ns/day (lagging wrt GPS)

L350

L350-1 appears locked and synchronized
L350-2 appears locked and synchronized.

No loss of lock or sync since last reboot on either unit

L359

Both units appear locked

L358

Presently running on EMR-1 (L350-1, L359-1)

---------------------------------------------------------------------

Based on these (without doing any possibly destructive testing) it 
appears that the Master Rack timing is normal, and that it is safe to 
proceed with WIDAR work.
