R. Beckerszendy et al., STUDY OF UNDERGROUND MUONS DURING THE JANUARY 1991 RADIO FLARE OF CYGNUS-X-3, Physical review. D. Particles and fields, 47(10), 1993, pp. 4203-4205
Muons recorded by the IMB proton decay detector during the radio outbu
rst from Cygnus X-3 in January 1991 are studied. Data are examined for
both aperiodic excesses and those phase modulated at the x-ray period
of Cygnus X-3. No correlation between the muon data and Cygnus X-3 is
found. Further, this observation provides flux limits of PHI90% C.L.
