... For full UV energy Euv (erg) radiated in TLE the corresponding number of photons of wavelength =300-400 nm (with average energy 3.5 eV) is: Nph=Euv/3.5в1.6 10-12 (1) We considered 2 options of the pinhole camera focal distance: 1. focal distance is short so that the circle of diameter 40 km is observed by one pixel and 2. focal distance is long so that the 40 km circle is observed in many camera pixels. ... Full energy released in UV in the atmosphere is determined by the pixel signal. ...
