Solar Activity
Choice of the solar activity files
OPERA needs solar activity data as input of its atmospheric model. These data will take place both in:
- a file including actual solar activity (i.e. in the past)
- a file including foreseen activity (i.e. in the future)
By default, the files will be taken directly in the jar file; that is why the path will start with "/" corresponding to the jar root where a solar/ directory is already existing and containing these both files. Anyway, it is possible to search for other files using the 
buttons that wil open a browser.
The value of the date interval of each file is automatically indicated below the entry area.
Choice of the merge method
Once the solar activity files selected, the user may choose when OPERA will switch from a file to another one. By default, the merge will occur at the end of the actual data but it will be possible to change this date (with a value before the last date of course!).
