A set of volume-rendered images of the astrobinary shows that the pair exhibits a similar attenuation variation pattern indicative of the highest density of material at the core and the lowest density of material at the outermost layer. The images were produced by sequentially varying the display transparency within the range defined by high (Figure 3(b)) and low (Figure 3(a)) thresholds. Volume: 157.50 × 173.25 × 425.25 nm³.
