High resolution spectra of the Silicon at 5665 Å and 5684 Å in the Sun

We present a dataset of high resolution spectra of the Sun of the SiI lines at 5665.563 Å and 5684.5 Å. These solar spectra (resolution respectively of 11.153 mÅ and 10.995 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 Silicon abundance. The spectra shown here are freely available in FITS format to the research community.
