Dear Colleagues,
We have one other announcement regarding the recent receiver swap at Gilmore Creek
Observatory, Alaska (FAIR). Right after the swap the new ASHTECH UZ-12 receiver was
running off its INTERNAL clock (not the H-Maser) for the first two days. This is
reflected in sections 6.4-6.5 in the updated log, but is repeated here for your
convenience:
6.4 Standard Type : INTERNAL
Input Frequency : (if external)
Effective Dates : 2004-11-25/2004-11-26
Notes : Internal clock used after reciever swap.
: Actual start date 2004-11-25T02:30Z
: Actual end date 2004-11-26T21:30Z
6.5 Standard Type : H-MASER
Input Frequency : 5 Mhz
Effective Dates : 2004-11-27/CCYY-MM-DD
Notes : Actual start date 2004-11-26T22:30Z
This data has also been made public. The new ASHTECH UZ-12 receiver was again running
off the EXTERNAL H-Maser starting on 2004-11-26T22:30Z.
We apologize for the inconvenience this may cause.
Maintenance and operations of the FAIR station is a collaborative effort supported by
JPL, UNAVCO, and Gilmore Creek Observatory (NOAA), with funding provided by NASA's
Earth Science Enterprise.
Best Regards,
-Oivind Ruud
