SNDICE: A Calibrated Multi-Wavelength Light Source for Optical Telescope Calibration with a Stability and a Precision of 10^-4
2010
Cosmological topics such as the study of Dark Energy, require a better photometric precision than what has been achieved until now. An accuracy better than 1% is at least necessary. To go in that direction, we have designed, constructed and installed at the Canada-France-Hawai’i Telescope (CFHT), a calibrated light source. The goal is to monitor and calibrate MegaCam, a wide field imager used by projects such as the CFHT Legacy Survey and the Supernova Legacy Survey (SNLS). The aim is to obtain an accuracy better than 0.1%.
