## Functions
hdrl_parameter * | hdrl_dar_parameter_create (hdrl_value airmass, hdrl_value parang, hdrl_value posang, hdrl_value temp, hdrl_value rhum, hdrl_value pres, cpl_wcs *wcs)
| Creates DAR parameters object with the values in the header.
cpl_error_code | hdrl_dar_compute (const hdrl_parameter *params, const hdrl_value lambdaRef, const cpl_vector *lambdaIn, cpl_vector *xShift, cpl_vector *yShift, cpl_vector *xShiftErr, cpl_vector *yShiftErr)
| Correct the pixel coordinates of all pixels of a given pixel table for differential atmospheric refraction (DAR).
hdrl_value | hdrl_dar_owens_saturation_pressure (hdrl_value hvT)
| Compute the saturation pressure using the Owens calibration.
hdrl_value | hdrl_dar_filippenko_refractive_index (hdrl_value hvL, hdrl_value hvP, hdrl_value hvT, hdrl_value hvF)
| Compute the refractive index for the given wavelength following Filippenko formulae. This function is called by hdrl_dar_compute().
