      abstract     = {An efficient way to study the QCD phase diagram at small
                      finite density is to extrapolate thermodynamicalobservables
                      from imaginary chemical potential. The phase diagram
                      features acrossover line starting from the transition
                      temperature already determined at zero chemical potential.In
                      this talk we focus on the curvature of this line at mu = 0.
                      We present the extrapolation ofthe crossover temperature
                      based on three observables at several lattice spacings. The
                      simulationswere performed at zero and at moderate values of
                      the imaginary chemical potential, always in thestrangeness
                      neutral point. We used the Symanzik-improved gauge action
                      with four times stoutsmeared staggered fermions.},
