Paper Abstract

A dedicated code designed to simulate observations made with a high contrast imaging instrument using an integral field spectrograph and an extreme adaptive optics system (CHEOPS) is in progress. High contrast and high angular resolution are required in order to detect close faint companions and exo-planets using the differential technique. In this paper we present a comparison, made in order to validate the code, between simulations and observations recently obtained with the Simultaneous Differential Technique (SDI)\cite{len03}, an up-graded version of NACO (AO facility at the ESO-VLT 8m telescope "Yepun").
