We consider four-dimensional dyonic single-center BPS black holes in the N=2 STU model of Sen and Vafa. By working in a region of moduli space where the real part of two of the three complex scalars S,T,U are taken to be large, we evaluate the quantum entropy function for these BPS black holes. In this regime, the subleading corrections point to a microstate counting formula partly based on a Siegel modular form of weight two. We also explore connections to the rational Calogero model which has been suggested before as a conformal quantum mechanical model relevant to black hole microstate counting. Based on work with Gabriel Cardoso and Davide Polini as in 1903.0586.
