Let,, and letbe the average offover the sphere with radiustcentered atx. For a subsetEof [1, 2] we prove close to sharpestimates for the maximal function. A new feature is the dependence of the results on both the upper Minkowski dimension ofEand the Assouad dimension ofE. The result can be applied to prove sparse domination bounds for a related global spherical maximal function.
