Since programmable electronic calculators were first employed in marine navigation, a variety of formulae has been used for calculating astronomical refraction. As the choice is wide, some formulae have been selected from commonly used reference sources and their accuracy and suitability examined. No attempt has been made to assess the validity of...

... Raytracing might be performed over the complete interferometric procedure (reflection and direct paths) or only in the direct path for faster evaluation, in which case eq.(12) would be approximated as ℓ ≈ ant . Alternatively, in case raytracing software is not available, blind atmospheric models such as the Global Pressure and Temperature (GPT) [19], [20] can be used to obtain refractivity at the station ℓ and models such as those of [21], [22] can approximate the elevation bending . ...
