An efficient way to study the QCD phase diagram at small finite density is to extrapolate thermodynamical observables from imaginary chemical potential. The phase diagram features a crossover line starting from the transition temperature already determined at zero chemical potential. In this work we focus on the Taylor expansion of this line up to $μ^4$ contributions. We present the continuum extrapolation of the crossover temperature based on different observables at several lattice spacings.
