Dear colleagues,
The H-maser connected to the Z12-T receiver at BRUS presented
some problems during the week 2001.07.11 to 2001.07.17
A first jump was monitored as : 5.959 microsecond on doy 192, 12UT.
A second jump occured on doy 197, 12UT leading to bad observations and
finally a tracking interruption. The H-maser was then re-synchronized,
and restarted on doy 198, 13UT.
In addition we expect that there will be no data from BRUS between
24 and 31 july, because the receiver is participating to the
calibration campaign organized by the BIPM in order to determine
its hardware delays.
We apologize for these inconveniences,
P. Defraigne
