Figure 8: Comparison of the Doppler spectra of
Models 1 and 2 with the data at four nearby rotation phases.
Above each spectrum is the model's pole-on silhouette as seen
from the north pole with the radar toward the bottom.
Each silhouette is drawn at the same scale as the Doppler
frequency axis and at the indicated rotation phase. The
Doppler spectra can be thought of as scans of radar brightness
in the plane of the sky taken through a slit parallel to the
target's projected spin vector.
