Astro Calculator

The astro-calculator converts astronomical coordinates from one system to another.

The Astro-Calculator is opened by:

  • clicking the  "Tools" Toolbar button, and selecting  "Astro Calculator..." from the menu,
  • selecting "Tools" |  "Astro Calculator..." from the main menu.

When the astro-calculator is opened it is preloaded with coordinates appropriate to the tableau or current operation of the software. Changing the data in any field results immediately in a corresponding alteration to data in equivalent fields.

The astro-calculator is sensitive to the effect of precession on stellar coordinate systems.
