Abstract

The paper presents a description of the work of detection and identification of frequency lines in the Virgo dark fringe data from run C7. A number of methods are highlighted by which noise frequency lines are detected by data analysis and measurements in the laboratory. In this paper we give a description of the list of noise line candidates provided by the pulsar search analysis, the investigation of 10 Hz ( and harmonics) noise, violin modes, noise from the end station buildings'' air conditioners, sidebands in calibration lines and aliasing in the 4 kHz reconstructed data.
