CADOR and TAROT: a virtual observatory

Abstract

TAROT (Telescope Action Rapide pour les Objets Transitoires - Rapid Action Telescope for Transient Objects) is a network of two robotic ground based telescopes. The telescopes are fully automated, from the scheduling of the observation requests to the processing of the data. All the applications use a specific automated processing pipeline which has been continuously improved. CADOR (Coordination et Analyse des Donnees d'Observatoires Robotises - Coordination and Data Analysis of Robotic Observatories) is a set of data base servers which manage TAROT telescopes. CADOR is the prime interface to request new observations from TAROT and to access all images saved with the possibility to make additional processing and analysis. Tarot and Cador are compliant with Virtual Observatory standard and protocols.
