This page basically lists a couple of useful information to create good schedules
If you have troubles reading anything in the GUI simply change the window size.
Save your station network if you use it several times.
By clicking Load SCHED parameters you will always load the last used scheduling parameters.
Always write log files. This makes it easier to understand current results and the Matlab Command Windows stays clean.
You do not need to display the sky coverage via the checkbox in the GUI. This plot is also saved in your output directory.
Always make sure you use the newest catalog files.
Use the mutli scheduling tool!
Simulate your results. A high number of observations does not generally mean the schedule is better!
optimization conditions can help avoid single baseline scans.
use the iterative approach for optimization conditons
Always create and use a new source file unless you have a good reason not to do. This should be checked in the GUI all the times.
If something is not working or you have a question write us an email.
If you use the multi scheduling tool, use parallel processing.
The weight factors in the param.txt file are the most important factors to create a good schedule
Trying different weight factors via the multi scheduling tool is very easy.
As a start use the following factors:
for a regional network like the Austral stations try
for a global network try:
only the relative ratio between the weight factors is important! (PARA.WEIGHT_NUMBER_OF_OBS 1, PARA.WEIGHT_SKY_COVERAGE 2, PARA.WEIGHT_SCAN_END_TIME 4 will give the same result as PARA.WEIGHT_NUMBER_OF_OBS 10, PARA.WEIGHT_SKY_COVERAGE 20, PARA.WEIGHT_SCAN_END_TIME 40)
If you have a global network use subnetting
If you have a regional network do not use subnetting
the minimum station number should be always 2, except you have good reasons
use the optimization conditions to avoid single baseline scans
Use PARA.FILLINMODE 1 unless you have a good reason to use 2 or 12. Using 0 is never a good idea.
Usually around 100 sources should be enough to create a schedule.
Check your Matlab Command Window (or body.txt) if you have any 0-scan subnets. If this happens you do not have enough sources. Try to run the schedule again with a lower minimum flux density or reduce the PARA.MIN_SRCRP value (it is maybe better to reduce the PARA.MIN_SRCRP value)
It might help to reduce the PARA.MAXSLEWTIME a bit, but it is generally better to simply increase the PARA.WEIGHT_SCAN_END_TIME instead
All other parameters are not very critical. Only make sure that you do not have to high conditions for this parameters. (like a PARA.MAX_WAIT of 10 would yield to a problem, or a PARA.MAXSLEWTIME 10… it is generally better to use high numbers here and not to constrain anything here)
Check if you have any 0-scan subnet in your Matlab Command Window or in your body.txt.
