Abstract:
GRAPES-III experiment [Tonwar S.C] consists of 271 scintillators of 1 m2. area each and a large area (560 m2) muon detector to record Extensive Air Showers (EAS) produced in the atmosphere by high energy cosmic rays (> 3 x 10^13 eV). A comprehensive set of software modules have been developed to analyze this vast amounts of data (> 3 Giga byte/day). A brief description of this is presented here.
