Query: Measurement of cluster elongation and charge in a pixel detector of
  10~$\mu$m pitch at sub-GeV energies   We present measurements of elongation and cluster charge using MIMOSA-18 MAPS
pixel matrix with 10 $\mu$m pixel pitch, using electron test beams of energies
ranging from 15 to 500 MeV. We observe energy dependence of cluster charge and
elongation for large incident angles.
