Solar altitude calculation #111

Closed ekplesovskaya closed 5 years ago

ekplesovskaya commented 5 years ago

Hi,

Does the pysolar sun altitude accounts for refraction? I need to calculate the sun altitude for every minute of twilight. I noticed that between 0 and -1 degrees the sun altitude values change very fast. Could you explain, why there are not so much values between 0 and -1? Is it so because of refraction?
