All rows for this asteroid are exported.

Sorting: first by filter groups (U-like, B-like, V-like, R-like, I-like, IR), then by filter, then by phase angle.

The plot shows P_r, and if it is unavailable, P. Error bars use sP. The same reference is shown in the same color.

Marker shape encodes the filter group. Bottom legend: color = reference.
