They are called alignment marks, fiducials, fiduciary markers,
registration targets... lots of different things, depending on the lingo
of the user (printers, doctors, imagers, etc). Presumably they are
located at carefully controlled locations on the rover in order to
provide references for image geometry.

Greg, I think that those are alignment symbols (register marks?) and not
radiation symbols. Maybe someone on the list can provide the correct name for
them?
