Stations

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 2015 fiscal year, JADE session will be carried out once a month. 

NETWORK
=======
The standard configuration of the JADE projests consists of 
some stations.

SCHEDULE
========
This schedule was made by GSI using sked. 

Schedule setup parameters:
   Early start                     EA sec 
   Corr. tape sync time             sec 
   Minimum scan length              sec 
   Maximum scan length              sec
 Minimum SNR by baseline for multi-baseline scans
     X-band (margin   3)     S-band (margin   3)

 Ts  22  20          Ts  16  15
 Ud  22  20  20      Ud  16  15  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              206 seconds
   Median SNR                        35 at X-band
                                     25 at S-band
   Number of observations           893 observations
   Average scans per station        207 scans
