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 via 6 times sessions a year. 

NETWORK
=======
The standard configuration of the JADE projests consists of 
four stations. Shintotsukawa cannot participate winter season session.

Station:      Code   
Tsukuba       Ts
Aira          Ai

SCHEDULE
========
This schedule was made by S. Kurihara using sked. 

Schedule setup parameters:
   Early start                           20 sec 
   Minimum scan length                   70 sec 
   Maximum scan length                   764 sec
   Minimum SNR                           20 at X-band (margin 10)
                                         17 at S-band (margin 7)

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 20% of ranked scans for selection, 
   consider the last 4 hour of scans for sky coverage calculations,
   minimum 30 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              326 seconds
   Median SNR                       25.0 at X-band
                                    25.0 at S-band
   Number of observations           799 observations
   Average scans per station        150 scans
