Clock Synchronization
This is the same procedure described in Section 2 - ``Getting Started on the Workstations''. It is worth mentioning again, as often the workstations will already be up and running, but it is imperative that the clocks are checked before starting any fringe-finding or correlating.Before starting any fringe-finding or correlating, you must check that each and every S2 to be used is set to the same time as the master clock.
Check that the UT time on the master clock (clock on wall with big red letters) agrees with the UT displayed in the top right-hand corner of each S2 window. Double check that all S2 units agree with each other.
If the times do not agree, set the times correctly in each S2 window that is incorrect by typing;
s2 console | time hh:mm:ss |
And hitting return at the appropriate time corresponding to the Master Clock Display.
After a power-fail, it will be necessary to restart the master clock, which is located in the delay and fringe-rotator rack. Check with correlator staff if this is necessary.
