Tutorial: Radiance to Reflectance Conversion

SUN_ELEVATION = 58.89832762
SUN_ZENITH = (9058.89832762)=31.1016724

EARTH_SUN_DISTANCE = 1.0085455

Band 2 : 2067
Band 3 : 1893
Band 4 : 1603
Band 5 : 972.6


Rblue=(PI * blue * pow(1.0085455,2)) /(2067*cos(rad(31.1016724)))

Rcblue=Rblue /cos(rad(31.1016724))
