摘要: The 2nd generation VLT instrument SPHERE will include an integral field spectrograph to enhance the capabilities of detection of planetary companions close bright stars. SPHERE-IFS is foreseen work in near IR (0.95-1.65 micron) at low spectral resolution. This paper describes observing strategies, adopted hardware solutions for calibrating instrument, and data reduction procedures that are mandatory the achievement extreme contrast performances which designed.
