| U7122 | 2 May 2007 | 14:30-15:30(UT) | 128Mbps |
- K5 Data at Kashima 34m telescope were recorded with K5/VSSP sampler.
- Mark5 Data from Onsala 20m telescope were transfered in real-time with
tsunami protocol, and recorded in the server at Kashima.
- Data Rate was reduced to 128Mbps for the reason to fast
processing. Though there was a trouble in 64Mbps recording in the
previous experiment.
- Data conversion from Mark5->K5 has performed by M5tok5 software
developed by T.Kondo (NICT).
- Correlation processing was applied for the data with software
correlator developed by T.Kondo.
- New
Above data conversion and correlation processing were run on
different PCs. And they are invoked by
timing-control software (conv_tool4.pl and cor_srv1.pl: perl
script) communicating with TCP/IP.
- New
Correlation processing was
performed in parallel with
observation. This is realized by using K5/VSSP32.
- New Owing to above improvement of
in parallel & distributed processing, the correlation
processing was finished within 10 min. after the
observation. And the UT1 result was prospected to be obtained
within 30 min. after the observation.
- U7122 experiment was basically successful, but due to minor
problem in analysis, UT1 solution was obtained in a few days
after the experiment.
- It was found that a problem of PLO-Unlock has been occurred in the
experiment and 1-2 scans were lost due to the trouble.
