ID:: ivo://edu.gavo.org/eurovo/cosadie_star_clusters
Title:: Star clusters
Date:: 27 Dec 2024 08:31:13
Publisher:: The GAVO DC team
Description:: Within this use case you learn about the difference between intrinsic linear size and apparent angular size, a difference that is frequently at the center of astronomical problems. Star clusters are the objects used to illustrate this difference. You also learn some basic facts about star clusters, whose distribution in space has helped us to understand the structure of our Milky Way. Thanks to Aladin, you will be able to explore their distribution on the sky on your own.

ID:: ivo://org.gavo.dc/stctrans/q/utypes
Title:: STC utype generator
Short Name:: stcs to utype
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: This services converts the representations of STC objects in XML, utypes, and STC-S into each other.

ID:: ivo://edu.gavo.org/eurovo/cosadie_stellarium
Title:: Stellarium for Beginners
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: Within this use case you learn about Stellarium's main features, each presented with examples taken from its most common use.

ID:: ivo://org.gavo.dc/misc/tapexamples
Title:: TAP examples endpoint
Date:: 09 Aug 2024 10:02:04
Publisher:: The GAVO DC team
Description:: This draft standard describes a means to present usage examples for TAP services in a way that is partially machine readable while primarily being consumable by humans. This is now part of DALI; identifiers created as fragments into this record are invalid and must now point to fragments of http://www.ivoa.net/rdf/examples.

ID:: ivo://edu.euro-vo.org/extern/asterics_collinder69
Title:: The Collinder 69 open cluster
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: 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.

ID:: ivo://edu.gavo.org/eurovo/cosadie_zodiac
Title:: The Constellations of the Zodiac
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: 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.

ID:: ivo://edu.gavo.org/eurovo/cosadie_milkyway
Title:: The Disc of the Milky Way
Date:: 27 Dec 2024 08:31:03
Publisher:: The GAVO DC team
Description:: 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.

ID:: ivo://org.gavo.dc/misc/adqlref
Title:: The GAVO ADQL Reference Card
Short Name:: GAVO ADQL ref
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
Description:: 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.

ID:: ivo://org.gavo.dc
Title:: The GAVO data centre
Short Name:: GAVO DC
Date:: 29 May 2024 06:02:44
Publisher:: The GAVO DC team
Description:: The GAVO data centre provides VO publication services to all interested parties on behalf of the German Astrophysical Virtual Observatory.

ID:: ivo://edu.gavo.org/hd/puzzlers
Title:: The GAVO VO Puzzlers
Date:: 27 Dec 2024 08:31:00
Publisher:: The GAVO DC team
Description:: 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.
