We study the  2 corrections to the quenched limit of  > 0 QCD. We use an improved reweighting procedure.
Introduction In Fig. 1 we sketch tentative fea-
tures of the QCD phase diagram in the ; ; T
space. Since a general description is missing, one
may try to concentrate on special situations, such
as the \quenched" limit [1] (see below), repre-
sented by the thick vertical dashed line at innite
 in the  = 0 plane. For a more physical sit-
uation we consider a vertical plane at small but
non-zero , then, e.g., a possible transition would
