Function Documentation

apply_tp_correction()

auto astro::earth::refraction::detail::apply_tp_correction ( const toolbox::AngleDeg & r_native, const Params & params )->toolbox::AngleDeg

inlinenodiscard

Apply the standard temperature/pressure correction to a native refraction value.

Parameters

r_native	The refraction at 10°C/1010 hPa, in degrees.
params	The actual atmospheric conditions.

Returns

The corrected refraction, in degrees.

Note

Meeus scales refraction by (P/1010) * (283/(273+T_c)).

validate_params()

auto astro::earth::refraction::detail::validate_params ( const Params & params ) ->void

inline

Validate refraction parameters are finite and above the numerical pole at −273°C.

Exceptions

std::invalid_argument

If temperature is not finite or ≤ −273°C, or pressure is not finite or non-positive.
