A sheaf $ F $
on an analytic space $ X $
such that for any point $ x \in X $
the set $ F _ {x} $
is a module over the ring $ {\mathcal O} _ {x} $
of germs of holomorphic functions at the point $ x $,
and such that the mapping $ (f , \alpha ) \rightarrow f \alpha $,
defined on the set of pairs $ ( f, \alpha ) $
where $ f \in {\mathcal O} _ {x} $,
$ \alpha \in F _ {x} $,
is a continuous mapping of $ {\mathcal O} \times F $
into $ F $
for $ x \in X $.
