Estimate of Combined Muon/Calorimeter Trigger Rates

Rates of combined muon/calorimeter triggers have been studied. The study was based on PYTHIA simulation package and a collection of subroutines for approximate, but very fast estimation of trigger response. Rates of Independent muon and calorimeter triggers have been also calculated for a cross-check with detailed simulation. As a result a set of trigger thresholds is proposed to maintain the 1st level trigger output rate at 30 kHz. The thresholds are low enough to fulfil the CMS physics program presented in the CMS Technical Proposal.
