Vaknaam                                Virtual Observations

uitgebreide vaknaam Virtual Observations


To make students acquainted with virtual observatories and related issues.



In this course we will discuss modern astronomical virtual observatories. National and foreign lecturers will present various international Virtual Observatory (VO) systems.

The course starts with an introduction to information systems and how to use these to obtain astrometrically and photometrical calibrated astronomical images.

Two lecturers will present the European Virtual Observatory and one the UK AstroGrid virtual observatory.

The lectures will discuss the design of these virtual observatory systems, the principle concepts and how they work and connect users to  large databases, parallel computers, data archives, networks and  grid infrastructure. Lecturers will also explain how users can do their research with  the VO systems and during the practical assignments exercises will done using these systems.  Data acquired by students in December 2006 in La Palma will be processed and published in the AstroWise  VO system.

This course is supported by the EU through the European Virtual Observatory Data Center Alliance (Euro-VO DCA).
