ESTIMATED_CROSS_SECTIONS定数

The average cross-sections, in square metres, that this package assumes for the bright satellites it names by NORAD number: the ISS (25544), China's Tianhe (48274) and the Hubble Space Telescope (20580). They are rough working figures from the sizes space agencies publish (the ISS's solar array length of 73 m and wingspan of 109 m, Hubble's 13.2 m long and 4.2 m wide body with two solar arrays, Tianhe's core module about 17 m long and 4.2 m wide with two solar wings), not measurements: good to a factor of two or so, which is about a magnitude. Give your own, or a standard magnitude, to findPasses through its magnitudes option.
