The
linear extension on the right is scientifically reliable, based
on measurements of the rate of revolution of Sirius B around
Sirius A. The linear extension on the left is not scientifically
reliable. It is a presumed correlation, for there is no way
in which the rate of revolution of Digitaria can be known certainly
from the Dogon information. These linear extensions cannot,
therefore, be considered to constitute hard evidence of a correlation.
It is likely, though, that they do correlate because Digitaria
is presumed to move at a rate which makes astronomical sense
(for if the shape of the orbit and the distance match, the period
should match)
