Pressure = Solar coeff / speed of light (1 + Coeff_reflectivity) v cos^2(gamma) = = 1367/3e8 (1+0.8) 1 cos^2(0) = 0.000008202 Pa

gamma = 0 (SSO orbit, always facing the sun) Coeff_reflectivity = 1.8 from the Tolosat.csv definition file Solar Coefficient is 1367 W/m^2 at 1 AU

with v the shadow function (0 in shadow, 1 in sunlight), hence the 1 here.
