Abstract: Under the axiom that no measurable cardinal exists it is proved that " $ {(F \cap G)_\sigma }$-measurable" maps of a hereditarily Baire and Čech analytic (e.g., compact) space into a metric space has the point of continuity property. A result on completely Borel-additive families in Čech analytic spaces is the crucial part of the proof.
