Muon measurements with MACRO. [4u 0115+63M1; Her X-1; NGC 1952; 4U1907+09; Cyg X-1; Cyg X-3; 1E 2259+59]

The large size, good pointing resolution and fine grain of the MACRO detector make it a powerful tool for studying interactions of very high energy cosmic rays through the high energy muons ([ital E][gt]1.3 TeV) resulting from decays of energetic pions and kaons. Results are presented on muon astronomy, cosmic ray composition studies and interaction model studies.
