Query: Luminosity Measurement Method for the LHC: Event Selection and Absolute
  Luminosity Determination   Absolute normalisation of the LHC measurements with O(1%) precision and their
relative normalisation, for the data collected at variable centre-of-mass
energies, or for variable beam particle species, with O(0.1%) precision is
crucial for the LHC experimental programme but presently beyond the reach for
the general purpose LHC detectors. This paper is the third in the series of
papers presenting the measurement method capable to achieve such a goal.
