Photometric precision
WebJun 8, 2024 · Photometric accuracy is limited to 5-10% due to uncertainties in the atmospheric extinction over Cerro Pachon, flat-fielding and sky subtraction, and the precision in the gain determination for each of the arrays. If the user is aiming at a higher photometric precision, it is necessary to self-calibrate the images, detector by detector. WebWe demonstrate a path to hitherto unachievable differential photometric precisions from the ground, both in the optical and near-infrared (NIR), using custom-fabricated beam-shaping diffusers produced using specialized nanofabrication techniques. Such diffusers mold the focal plane image of a star into a broad and stable top-hat shape, minimizing photometric …
