High resolution spectra of Lithium LiI D1/D2 lines at 6708 Å in the quiet Sun: centre to limb variation

We present a dataset of high resolution spectra of the Sun of the LiI lines D1 and D2, respectively at 6707.76 Å and 6707.98 Å. These solar spectra (resolution respectively of about 12 mÅ) were obtained in the quiet Sun at various distances from the disk centre with the ground based CNRS Themis telescope and are useful for the research of Lithium abundance. The spectra shown here are freely available in FITS format to the research community.
