1100 Days of BATSE Observations of Cygnus X-1
  We have examined the power spectral behavior of Cygnus X-1 using approximately 1100 days of BATSE data. These data have been searched for correlations between different power spectral features, and for correlations between power spectral features and energy spectral parameters derived from BATSE occultation analysis.
