By carefully choosing the shape of the aperture mask, you can avoid nearby contaminants or improve the strength of the specific signal you are trying to measure relative to the background.
WebOct 5, 2024 · The 30 minute diffuser-assisted photometric precision levels presented in this paper are now beginning to approach (and in some cases exceed) 80 ppm—the transit depth of an Earth around a Sun-like star, even in the presence of scintillation noise. We stress that diffusers can be used to improve the precisions across different telescope apertures.
