Query: Eclipse mapping of the stream and disk flickering components in V2051
  Oph   We report on the investigation of the spatial distribution of the flickering
sources in the dwarf nova V2051 Oph with eclipse mapping techniques.
Low-frequency flickering originates in the gas stream and is related to the
mass transfer process, whereas high-frequency flickering arises in the
accretion disk and is probably connected to magneto-hydrodynamic turbulence.
