Version 2.0.2 of AstroGrav has the following new and improved features.
View Window Improvements
Version 2.0.2 of AstroGrav includes the following improvements and bug fixes to the operation of view windows.
- There have been several improvements made to the display of ecliptic grids and equatorial grids. The details of these improvements can be found below.
- In solar system simulations, ascending node indicators and descending node indicators have been added to the orbits of selected objects that have the Sun as a parent.
- The magnitude key has been made much more useful by making the magnitudes of the key stars sensitive to the magnification and brightness.
- The crosses indicating selected objects have been made visible regardless of whether or not the object itself is bright enough to be visible.
- A bug has been fixed that caused AstroGrav to crash when viewing from the single object in a simulation with just one object.
- Trajectory drawing and history drawing have been significantly speeded up.
- A bug has been fixed that caused some history values to disappear near the edge of a window.
Coordinate Grid Improvements
Version 2.0.2 of AstroGrav includes the following improvements and bug fixes to the display of ecliptic and equatorial coordinate grids on view windows.
- The display of ecliptic grids and equatorial grids has been greatly speeded up at high magnifications.
- More ecliptic grid lines and equatorial grid lines are now displayed at low magnifications.
- A bug has been fixed that caused some angle labels on the ecliptic and the equator to not be displayed when they should be.
- A bug has been fixed that caused angle labels on the ecliptic and the equator to jump from one side of the line to the other at low magnifications.
- The orientation of the angle labels used for the ecliptic and the equator have been changed from parallel to horizontal.
Object Import Improvements
Version 2.0.2 of AstroGrav includes the following improvements and bug fixes to the Edit / Import Objects... command.
- A bug has been fixed that caused the fragment codes of comets to be missing from comet import tables.
- In asteroid import tables, the Name column has been renamed the Designation column.
- In asteroid import tables, the default sort column has been changed from the Number column to the Designation (previously Name) column.
- In asteroid import tables, sorting on the Designation column has been greatly improved to make it more intuitive and easier to manually search for a particular asteroid.
Other Improvements
Version 2.0.2 of AstroGrav also has many other minor improvements and bug fixes, including the following.
- A bug has been fixed that could cause an edited orbital period to become corrupted when using the object editor.
- The Tau Ceti sample simulation has been added in order to illustrate the system of five planets that have recently been found to be orbiting the star Tau Ceti.
- In most of the sample simulations in the Abstract Systems and Exoplanet Systems, the origin of the reference frame has been made stationary at the center of mass.
- The documentation has been updated to cover the recent improvements.
