Abstract: In a recent paper Folsom and Ono constructed a grid of Poincaré series of weights $ 3/2$ and $ 1/2$. They conjectured that the coefficients of the holomorphic parts of these series are rational integers. We prove that these coefficients are indeed rational numbers with bounded denominators.
