AVGCHAN
Type: Adverb   (Real)
Use:  Controls whether and how spectral channels are averaged.
Null value:  Usually <= 0 -> no averaging.
Tasks:
  RFLAG....Flags data set based on time and freq rms in fringe
           visibilities.  AVGCHAN specifies the width of the median
           window used in the spectral flagging mode.
  VPLOT....Plots visibilities one baseline at a time.  AVGCHAN
           controls whether spectral channels are averaged or
           displayed separately.
