Reflectance spectrum of the Athor family and meteorites. (A) Average spectra of Athor and Zita family members, which are clearly distinct, while the curve-matching of EL spectra with the average Athor family spectrum is evident. For comparison, we present three spectra of two EL6 meteorites, Hvittis and Pillistfer, that best-matched with the Athor family. (B) 1.8/0.8 μm reflectance ratio versus the geometric visible albedo of the Athor family and the individual meteorite spectra (CM2 and CV) that achieved a curve-matching with Athor in the first step of the analysis. Another curve-matched meteorite is a bright enstatite achondrite (aubrite) that lies out of the range of the plot (Table B.3). For ELs and EHs, we present the respective averages. The properties of the Athor family members and the ELs overlap, whereas the other meteorite classes are clearly distinct.
