Remember : LJ will automatically warp geometry according to alignement data. See webUI.
|
||||
|
||||
Todo:
|
||||
|
||||
- Validate aa2radec() with online calculator. Rewrite it to remove need for Astropy.
|
||||
- Findout how to use OSC in python 3.
|
||||
- Code WebUI page.
|
||||
- UpdateStars() in each laser sky. Get magnitude. See UpdateSolar for example.
|
||||
- Draw operations should also check visibility in the given laser altitude range.
|
||||
- Rewrite CityPosition() with proper search in a python dictionnary.
|
||||
- Better python code. Better varuable to understand easily Update() methods.
