Field optimization and CCD data simulation for the antarctic International Concordia Explorer Telescope (ICE‐T)
Abstract We performed extensive data simulations for the planned ultra‐wide‐field, high‐precision photometric telescope ICE‐T (International Concordia Explorer Telescope). ICE‐T consists of two 60 cm‐aperture Schmidt telescopes with a joint field of view simultaneously in two photometric bandpasses....
