CH3OH and H2O masers in high-mass star-forming regions
  We present a comparison of ClassII CH3OH and H2O masers at high spatial resolution in a sample of 29 massive star-forming regions. Absolute positions of both maser types are compared with mm dust continuum, cm continuum and mid-infrared sources. Spatial correlations of the different tracers and kinematic signatures are discussed.
