Mandate

    The purpose of the ATLAS luminosity measurement taskforce is to:

  • Identify, document and characterize the performance of the various online luminosity algorithms;
  • Provide an initial absolute Monte Carlo based calibration;
  • Identify and quantify the possible systematic errors in the luminosity measurements;
  • Identify and document the improvements that can be made in an offline anlysis;
  • Propose offline archiving and accounting strategies.

    The full mandate of the taskforce is avilable here.
