Typical XSL DR2 spectra
The XSL DR2 spectra were released on January 10th 2020: 813 observations of 666 stars covering the full wavelength range UVB to NIR (see Gonneau et al. 2020 for more details). Stellar parameters for 754 observations were also determined (Arentsen et al. 2019).

* Low [Fe/H] means [Fe/H] < -1.5 in our case. No correction for extinction was applied.
