The Sun Data Manager
At the top left of this dialog, there are buttons that are used to Export Sun data using the MS-Excel format. Further to the right are buttons used to Add, Delete or Modify the source currently selected in the list of sources.
Note that the Sun Data Sources that are part of the Q++Studio World Holidays Sample Database are shown in a lighter font, as shown below.
These Sun Data Sources cannot be modified, and you should not use them in any of your scripts.
