Sun Data Sources
Sun Data Sources are created in the Sun Data Sources Manager which are based on astronomical calculations use the specifics of an observer's position to calculate when various Sun events will occur as seen from that geographical position.
The Name field is used to identify the Sun data source with a geographical location.
You can use the lookup button on the left to select a city and its Coordinates from the list of 2000 cities that ships with Q++. Additional cities and locations can be obtained at www.calle.com/world/index.html which contains data on almost 3 million locations. If you have already created a location for another type of data (Lunar, Jewish, Muslim) then you can use the lookup button on the right to clone the coordinates and summer time information from that other location.
If a location follows Summer Time rules, then you should always specify its rules here, even if you do not wish to have the Sun Tokens values affected by changes in summer time. You can always, for each specific script set the option Ignore Summer Times, even if source uses them in the Sun Data Source property to ignore summer time rules for a given script.
