^aG-CD155-PV1 represents the fitted model in the density of glycosylated CD155 complexed with PV1. Similarly, D-CD155-PV1 refers to deglycosylated CD155.

^bH/N is the peak height in the carbohydrate difference map with respect to the noise. The mean density height of the difference map is 0. The noise is the biggest noncarbohydrate peak in the difference map.
