Unlike mirrors, they do not require high precision polishing or positioning, and can be used in a large domain of wavelengths from far IR to far UV, enabling the study of many science cases in astrophysics from exoplanet surfaces and atmospheres to galaxy evolution....
D represents the Earth-to-Sun distance; E0 denotes the mean exo-atmospheric solar irradiance; θ represents the solar zenith angle; and π = 3.1415926. Furthermore, atmospheric correction is conducted using the 6S model (i.e., the second simulation of the satellite signal in the solar spectrum...
