The Astro::ADS module is an objected orientated Perl interface to the
Astrophysics Data System (ADS) abstract service. The ADS is a NASA-funded
project whose main resource is an Abstract Service, which includes four sets
of abstracts:
1) astronomy and astrophysics, containing 719,449 abstracts;
2) instrumentation, containing 608,834 abstracts;
3) physics and geophysics, containing 1,079,814 abstracts; and
4) Los Alamos preprint server, containing 4,104 abstracts.
Each dataset can be searched by author, object name (astronomy only), title,
or abstract text words.
The module is an object orientated interface to the both the first and second
Digital Sky Surveys at the ESO-ECF online archive. While the first sky survey
is 100% complete, the second survey covers 98% of the sky in Red, 45% of the
sky in Blue and 27% of the sky in the Infra-red.
The Astro::SIMBAD module is an objected orientated Perl interface to the
SIMBAD astronomical database. SIMBAD provides basic data, cross-identifications
and bibliography for astronomical objects outside the solar system.
The SWISS EPHEMERIS is the high precision ephemeris
developed by Astrodienst, largely based upon the DE406
ephemeris from NASA's JPL.
Developers can license the Ephemeris library.Ephemeris
users find 3200 years of read-made printable files of
ephemerides, containing 19'200 print pages in PDF quality.
The Swiss Ephemeris is available under a dual licensing
model: GPL2 or Swiss Ephemeris Professional License.
This dockapp shows you the actual distance of Jupiter in astronomical units
(AE) and when the red spot crosses (which is a weather feature on Jupiter).
The four Galileo Moons are displayed too but only when they are near the
planet (Io, Europa, Ganymede, and Callisto). The position of the red spot
changes on the surface so you need to change that value within few months
or so. The current position can be found on the Internet. It was 80 deg.
as of 11th Jan 2002.
It shows you the solar system viewed from top (90 heliocentric).
The objects have the following colors:
Sun - yellow Mercury - green
Venus - white Earth - cyan
Mars - red Jupiter - gray
Saturn - green Uranus - pink
Neptune - cyan Pluto is not included since it's way "off course"
A left click on the window changes the view between inner and outer planets.
A left click on the date increases the day/month/year. A right click on the
date does the opposite. Click the right mouse button on the solar system to
reset the date to the current date (which is in Universal Time).
Displays a rendered view of the earth in your root window, similar to
xearth, but instead uses a satellite image map of the earth. You can also
substitute surface maps of other planets if you're feeling cosmic.
The xtide program predicts and displays tides. It is capable of
producing output in a variety of dynamic and static formats, and has
extensions for X, plain ASCII, and HTML.
abcselect is a perl script for extracting parts, movements
etc. from files in the abc format of music notation.
The asmixer utility is a mixer control for the X Windows environment. It
is designed to work with the AfterStep Window Manager, but it will
work with Window Maker or most any other Window Manager. It has
controls for three configurable channels which are master, pcm, and cd
volume by default.
