DSVG Sky runs in a web browser, provided it supports recent ECMAScript and SVG. Just click here and it should start.
If it does not work, ensure your web browser is modern enough. DSVG Sky is known to work with Firefox 2.0 and later. It probably will not work with any version of microsoft internet explorer.
If it still does not work, please let me know.
If you want to install DSVG Sky on your computer and be able to run it offline, you need to save the following files all in the same directory:
dsvg-sky.xhtml (3.9 ko) is the glue that fits all
together, and also holds the style information (colors of the sky
and planets...).dsvg-sky.js (26.6 ko) is the program itself.astronomical_data.js (40.3 ko) holds the numerical
data necessary to compute the position of the planets.
You also may want data_to_ecamscript (9.1 ko), a perl
script used to generate the astronomical_data.js file
from the VSOP87, ELP82 and SMART97 data that were once available on
the Bureau des Longitudes FTP site. These data seems to be still
available on the University of Strabourg FTP site:
VSOP87,
ELP82,
SMART97.
