Centre to limb spectra of Lithium (670 nm), Oxygen (630, 636, 777 nm) and Silicon (566, 568 nm) of the Sun, and Oxygen spectra (630, 636 nm) of brightest stars

This dataset contains high resolution spectra in FITS format got at the THEMIS (INSU/CNRS telescope).Centre to limb spectra of the Sun at various limb distance (about ten mu values) were got for Lithium D1/D2 lines (6708 A), Oxygen (forbidden lines 6300 A, 6363 A and the infrared triplet at 7775 A) and Silicon (5665 A, 5684 A).For comparison spectra of Oxygen (forbidden lines 6300 A, 6363 A) were got for the brightest stars with the same setup, for Aldebaran, AlpaPersei, Antares, Arcturus, Betelgeuse, Capella, Diphda, Hamal, Pollux and Procyon.The spectra may be used for research about abundances.
