If it is only required to do predictions then it is faster to use the Sun Outage Prediction Calculator

Green outline in outage footprint marks the 3dB beamwidth or the C/N link margin if Sun outage predictions is based on C/N degradation
NOTE:Inclination not accounted for in text predictions
Inclination accounted for when drawing affected area (based on 10min updates of inclination)
C/N calculations from ITU-R S.1525-1 & ITU-R BO.1506 simplified model
Be aware that the C/N calculations does not match ITU-R S.1525-1 & ITU-R BO.1506 100% with current implementation.
Also the radiation intensity from the Sun can be different from the average value used in the ITU papers
C/N reduction is less accurate for Ku antennas above 1.8m

ITU-R BO.1213 and ITU-R BO.1900 is used as reference antanna patterns. This patterns does not apply for C-band but due to the lack of C-band reference pattern the ITU-R BO.1213 is also used as pattern for C-band.
