Query: On C-fibrations over projective curves   The goal of this paper is to present a modified version (GML) of ML invariant
which should take into account rulings over a projective base and allow further
stratification of smooth affine rational surfaces. We provide a non-trivial
example where GML invariant is computed for a smooth affine rational surface
admitting no C-actions. We apply GML invariant to computation of ML invariant
of some threefolds.
