ABSTRACT. Let Z ⊆ P1 × P1 be a set of fat points thatis also arithmetically Cohen-Macaulay (ACM). We describehow to compute the degree of a separator of a fat point ofmultiplicity m for each point in the support of Z using only a numerical description of Z. Our formula extends the case of reduced points which was previously known.
