apply_refraction¶
- rubin_sim.utils.apply_refraction(zenith_distance, tanz_coeff, tan3z_coeff)¶
Calculted refracted Zenith Distance
uses the quick PAL refco routine which approximates the refractin calculation
@param [in] zenith_distance is unrefracted zenith distance of the source in radians. Can either be a number or a numpy array (not a list).
@param [in] tanz_coeff is the first output from refraction_coefficients (above)
@param [in] tan3z_coeff is the second output from refraction_coefficients (above)
@param [out] refracted_zenith is the refracted zenith distance in radians
