- Abstract
The Ring effect is measured using the UV-visible spectrometer (∼1 nm spectral resolution) of OSIRIS, the optical spectrograph and infrared imaging system. The observed filling in of Ca(II) H and K (∼395 nm), the two largest Fraunhofer lines in the solar spectrum, are compared with the filling in simulated with a new model that includes rotational Raman scattering (RRS) by N[SUB2] and O[SUB2]. The filling in is (1.06 ± 0:60)% at Ca(II) K and (1.40 ± 0:50)% at Ca(II) H for blue-sky observations at a solar zenith angle of 37°. The measured filling in agrees with the modelled filling in within the uncertainties.
