The tutorial uses VOSA to analyse members of the Collinder 69 open
cluster by crossmatching a given local set of objects and accesses VO
services to crossmatch the objects with 2MASS to receive colors. The
resulting SEDs are analysed using different fit functions.
Within this use case you learn about the constellations of the
Zodiac, i.e. those crossed by the apparent path of the Sun during the
year. Together with some characteristics the orbital motion of the
Earth, in this use case you also find a short excursion into history
of astronomy. The use case also introduces the precession of the
equinoxes.
Within this use case you discover the shape and thickness of the disc
of our own Galaxy by counting stars within and around the Milky Way.
With the use of both Aladin and Stellarium you draw the line
corresponding to the disc of the Milky Way in a coordinate diagram.
GAVO's ADQL reference card briefly gives an overview of the SQL
dialect used in the VO. It is available as a PDFfile and as Scribus
source under the CC-BY license.
The GAVO puzzlers are little training problems solvable by standard
VO techniques (data discovery, SIAP, Cone Search, TAP). They assume
some familiarity with common astronomical concepts (they were
originally given out during meetings of the German Astronomische
Gesellschaft) but are designed to be solvable using common, standard
tools and in reasonable time. Solutions are also given.
This tutorial employs the Aladin VO client to explore neutral
hydrogen shells around the SMC; it demonstrates using image servers,
catalog servers, and advanced overplotting within Aladin.
Within this use case you meet representatives of the most interesting
categories of celestial objects. From stellar clusters to galaxies.
All objects are from the Messier catalog that includes some of the
most viewed objects of the deep sky.
Within this case you discover the geometry of the orbit of the Moon
and the nature of its phases. As special case of the circumstances of
Moon's orbit, the use case introduces the eclipses, both of Moon and
Sun.
