PC2′ vs. PC1′ diagram from DeMeo et al. (2009). PC values calculated for 2013 CW32, 2016 CM194, 2017 WX12, 2019 SH6, and the metal-rich chondrite NWA 12273 (Reddy et al. 2019) are depicted with different colors. PC values for intimate mixtures of the L-chondrite Viñales and the iron meteorite Gibeon and intimate mixtures of Chelyabinsk and shock-darkened (SD) material from (Reddy et al. 2014) are also shown. Arrows indicate the direction in which the grain size or the content of metal and shock darkening increases. The first data point for the mixture of Viñales and Gibeon (lower right corner) corresponds to a mixture of 40 wt% Gibeon and 60 wt% Viñales. The following data points represent increments of 20 wt% Gibeon. The space-weathering vector from Binzel et al. (2019) is also indicated.
