    Marcel,


    Thank you for the additional information you gave on refraction at low altitudes and the reason why it is also very dependent on "aerosol content in the air".

    In his rencent post [NavList 11184] Frank E. Reed also gives very interesting complementary information on Refraction as related to Wavelenght.


    Merci encore,


    Kermit


    Antoine M. "Kermit" Couette
