Click on the menu item 'Select' to open the Selector
In the drop-down box next to 'Select one passage as reference for analysis:' select the 2nd entry,
which is 'Deliv10, Cirrus Delivery, Cirrus'.
Click the 'Submit Selection' button. Cirrugator is now preset to route the delivery of Cirrus.
Click on the menu item 'GRIB'
The 'GRIB file to show' is the most recent one; you typically want this. Click on 'All' to show all subsets. Click on the 'Go' button.
Take your time, look at each one of these GRIB plots, and try to understand what is going on.
Click on the 'WCharts' menu, then click the 'Go' button to see the up-to-date weathercharts of PSA, 48h surface, and 500mb.
Compare with the GRIB files.
Click on the 'Router' menu. The defaults are usually ok. Click the 'Go' button. After a few seconds you get the route.
Between the two graphs are two buttons. Click the 'Show/Hide Numbers' button. (Click again to make the numbers disappear). That's all what Cirrugator crunches up.
(Course is always TRUE, not Magnetic!)
In the little table to the right of the first graph is a summary of the red route fittingly named 'red' but typed in blue.
That's because it is a link. Click it to see the Route Inspection page: it shows the position of Cirrus in each of the consecutive
GRIB files, and let's you convince yourself that this position does make sense!
Last thing to do is to play with the options of the router. E.g. in the 'Settings:' box enter 7 for the 'No of routes' and click the 'Go' button again.
Look at the various routes and compare the Race analysis graphs (You may have to click the 'Show/Hide graphs' button)
