A method for rebuilding blended solar lines

Résumé

We propose a process for calculating water vapor absorption in solar radiation transmission through the atmosphere, in order to rebuild a true solar line profile, blended with telluric lines, with very good accuracy. First, we calculated a transmission profile using a spectroscopic data base. We then deduced the corrected line parameters by comparing the computed and observed profiles. An iterative method was applied to a solar spectral region around 1083 nm recorded at Kitt Peak. We showed that a relatively good fit may be obtained using an approximate atmospheric model and a simplifying assumption whereby all atmospheric, instrumental, and spectroscopic uncertainties are artificially assigned to the line parameters.
