Session JD1005
Start 2010-146 18:00:00 May 26
End 2010-147 17:57:26 May 27
Stations
1 Ts T TSUKUB32
2 S3 J SINTOTU3
Duration: 24 hours
Correlator: TSUKUBA(GSI)
PURPOSE
=======
The purpose of the JADE sessions is to monitor the plate motion and
the local crustal movement around Japan.
In 2010 fiscal year, JADE session will be carried out once a month.
NETWORK
=======
The standard configuration of the JADE projests consists of
some stations.
Code : Station
Ts Tsukuba
S3 Shintotsukawa
SCHEDULE
========
This schedule was made by tanimoto@gsi.go.jp using sked.
Schedule setup parameters:
Early start 0 sec
Corr. tape sync time 0 sec
Minimum scan length 30 sec
Maximum scan length 600 sec
Minimum SNR by baseline for multi-baseline scans
X-band (margin 0) S-band (margin 0)
Ts Ts
S3 20 S3 15
Automatic scheduling setup:
optimize for uniform sky coverage at all stations,
maximize the number of observations,
minimize slewing time,
minimize time between scans,
consider the top 0 of ranked scans for selection,
consider the last 0 hour of scans for sky coverage calculations,
minimum : min between scans on the same source.
The characteristics of the generated schedule are listed below.
These will vary slightly for each schedule that is generated.
Schedule characteristics:
Average scan length seconds
Median SNR 25 at X-band
20 at S-band
Number of observations 383 observations
Average scans per station scans
