Version 4.2.2 of AstroGrav has the following new and improved features.
Importing Objects
Version 4.2.2 of AstroGrav includes the following improvements to importing asteroids and comets with the Edit / Import Objects... command.
- A bug has been fixed that caused asteroids with epochs in the last quarter of a year to be placed in the wrong position when imported with the MPC Asteroids or MPC Asteroids (Daily) choices. If you used these options with AstroGrav 4.2.1, it's essential to refresh the data in order to replace the faulty cached data with the corrected data.
- The shortened name of the small body supplier (JPL, MPC, or Lowell) now gets appended to the name of an imported asteroid or comet, so that its origin is clear.
- The text labels for each of the small body suppliers have been changed to hyperlinks that lead to the appropriate web pages.
Other Improvements
Version 4.2.2 of AstroGrav also has several other minor improvements and bug fixes, including the following.
- The structure of a simulation has been made consistent with the Threshold setting in the Evolve / Settings... command.
- The error messages that are displayed when evolving to events with the Evolve / Evolve To... command have been greatly improved.
- The unwanted 'decimal digits' unit has been removed from the absolute magnitude input field.
