Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the James Webb Space Telescope's primary mirror is made of gold?

Yes. A reference encyclopedia entry states Webb's primary mirror segments are gold-plated beryllium with a gold coating for infrared reflectivity, and a NASA page describes the gold-covered primary mirrors. The claim is supported, though the mirror is gold-coated rather than solid gold.
