In our earlier work, the charge and matter radial distributions of heavy-light mesons were measured on a 16^3 times 24 lattice with a lattice spacing of a = 0.17 fm and a light quark mass about that of the strange quark. Several major improvements have now been made: 1) Dynamical fermions are used with a approximately 0.14 fm; 2) More gauge configurations are included (78 vs 20); 3) Off-axis, in addition to on-axis, insertions are made; 4) The data analysis is much more complete. In particular, distributions involving excited states are extracted.
