USING VIRTUAL OBSERVATORY TOOLS FOR ASTRONOMICAL RESEARCH

Journal of The Korean Astronomical Society, 2005
Construction of the Virtual Observatory (VO) is a great concern to the astronomical community in the 21st century. We present an outline of the concept and necessity of the va and the current status of various VO projects including the 15 national ones and the International Virtual Observatory Alliance (IVOA).

SearchCal: a virtual observatory tool for searching calibrators in optical long baseline interferometry [PDF]

Astronomy & Astrophysics, 2006
In long baseline interferometry, the raw fringe contrast must be calibrated to obtain the true visibility and then those observables that can be interpreted in terms of astrophysical parameters. The selection of suitable calibration stars is crucial for obtaining the ultimate precision of interferometric instruments like the VLTI.
