VDP OBJECTS

Object "VCUP" plots VDP profile. The number of Faraday cup to plot is specified in argument of the object.
Parametres:

    VCUP ""standard arguments"" # of Faraday Cup

The Y data range should be specified in terms of 1/cm^2 sec. I.e. number particles flux. Object plots only data picked with zero retarding potential. Object averages the data to reduce the number of points in one plot down to 1000.
Example:

  002
  vcup 0.0 0.1 0.9 0.3 0.0 0.0 -1.0e8 -5.0e7 0
  vcup 0.0 0.3 0.9 0.5 0.0 0.0 -2.0e7 2.0e7  2
