Compute STAR from the sun course directions given the following parameters:
:Parameters:
- `scene` : scene for which the STAR is to be computed
- `lat` : latitude of location, default = 43.36
- `long` : longitude of location, default = 3.52
- `jj` : Julian day, default = 221
- `start` : first hour to be considered, default = 7
- `stop` : last hour to be considered, default = 19
- `step` : time step in minutes between 2 sun positions, default = 30
- `dsun` : correction factor or something needs to be documented, default = 1
- `dGMT` : factor related to time zone needs to be documented, default=0
- `w` : width of viewer frame, default =150
- `h` : height of viewer frame, default=150
- `dfact` : distance factor for camera positioning i.e. 2.5 for 600x600 or 8 for 150x150, default=8
