How true is it in terms of astronomy?

Un Systeme Soudanais de Sirius (1950) and the more comprehensive Renard Pale (1963) contain astronomical data that are astounding if they are taken at face value as Dogon knowledge. Whoever authored them, they are incredibly imaginative, even for someone with state of the art knowledge in 1950, let alone for a tribe claimed to have had this knowledge since the 13th century.

Being poorly reproduced over the years has led to some confusion about what they actually are, so the astronomical data directly from Un Systeme Soudanais de Sirius and Renard Pale have been compiled into the following testable statements.

(From Un Systeme Soudanais de Sirius except as marked *Renard Pale)
