Computing Eclipses and Occultations

Topic map

workingupdated 2026-10-20

The map puts every topic of this site on one ring, grouped by section, with the home page at the centre and the sections on the rings between. A curve joins two topics when a page in one links to a page in the other, and a thicker curve carries more links. Curves of one or two links are hidden until the slider asks for them. Point at a topic, or move to it with the Tab key, to light its links and dim the rest. Click a topic, or press Enter on it, to keep it lit while you look, and click it again to open its page. Esc clears it.

The table under the map lists the same topics with their pages and the topics each one links to. The build draws both from the pages themselves, so a new link appears here at the next build.

Topic mapEvery topic on the site round a ring, grouped by section, with curves joining topics whose pages link to each other. A thicker curve carries more links. Each name is a link to its page.Method and source policy and Earth model and time scales: 1 linkMethod and source policy and Software and repositories: 1 linkMethod and source policy and Catalogues
