We show that if X is a Banach space of type 2 and G is a compact Abeli
an group, then any system of eigenvectors {x(gamma)}(gamma is an eleme
nt of (G) over cap) (with respect to a strongly continuous representat
ion of G on rr) is an RUG-system. As an application, we exhibit new ex
amples of RUG-bases in certain symmetric spaces of measurable operator
s.
