Using the inequalities for correction terms in Heegaard Floer theory we show constraints for singularities that can occur on a plane rational cuspidal curve. In particular we prove a conjecture by Fernandez de Bobadilla, Luengo, Melle--Hernandez and Nemethi. Generalizations apply for curves of higher genus.
