We present an update on our efforts to determine the Taylor coefficients for finite-density QCD. Here, we explore alternatives based on the Cauchy Residue Theorem, which allows us to use to use a discrete contour to determine moments emerging in the Taylor expansion of QCD at zero chemical potential.
