Frequency analysis of CI Cam.

Amplitude spectrum of CI Cam, calculated using Deeming method for the observations in V band.

Light curve of CI Cam V band. To draw this light curve, the observations were reduced to uniform system (of the photoelectric data by N.V.Metlova taken with V.M.Lyuty's electrophotometer at the SAI Crimean station), and then the trend of slow variability was eliminated.
