The PolarBase archive of stellar spectra
PolarBase is an online archive offering stellar data collected with the ESPaDOnS and NARVAL high-resolution spectropolarimeters, in their reduced form. All spectra feature a continuous coverage of the 370-1,000 nm spectral domain, at a spectral resolution of 65,000. As of 2022, observations of 4,700...
