CalEx : Catalogue of astrometric Calibrators for exoplanet hosting stars

Introduction

We provide here a list of calibrators for all stars with known exoplanets obtained using data mining and ”Virtual Observatory” techniques. The calibrators are found from catalogues available at CDS using SearchCal. In our test case, the calibrators are found within 1′ angular distance for approximatively 50% of the stars tested, and often closer. They are all faint objects from the 2MASS survey with K magnitudes between 13 and 15. A list of the most promising targets is given. In a next future, the same study will be initiated on much larger sets of potential targets.

Paper

One paper is in preparation to explain to method and objectives of this catalogue. The link onto the paper and the data will be given as soon as it is published. If you want to contact the authors, just email to the jmmc user support.

Data Products

The collection of retained calibrators can be read througth:

• a web page
• one VOTable (xml format enhanced for Virtual Observatory Interoperability)

For now access is restricted. If you want to get an earlier access or contact the authors, just email to the jmmc user support.
