BoPlanets V1.3 was released.
The new release contains improvements concerning the presentation of the equatorial and horizontal view. All views show the orbitals of the planets so, that maximum and minimum of the coordinates are close to the margins of the actual window. In former releases maximum and minimum declination, which are required for the equatorial and horizontal view, were approximated. This worked fine, if planet and observer were not adjacent.
In release V1.3 maximum and minimum declination is determined mathematically exact by using the numerical gradient method and the 2 dimensional Newton method.
Now all combinations of planet and observer with standard orbital parameters are fitting within the actual window size. This holds for most combinations of modifiable orbital parameters.
