Since no good theoretical model existed, all claims that reports of secondary occultations were common were disputed. B. Some of the reported observations of secondary occultations were actually observations of collisions of satellites with one another. C. If there were observations of phenomena exactly like the phenomena now labeled secondary occultations, astronomers were less likely than to have reported such observations. D. The prevailing standards concerning what to classify as a well-behaved secondary event were less stringent than they are now. E. Astronomers were eager to publish their observations of occultations of stars by satellites of asteroids.
