MODIFY SWITCH_MODE

        LAS\MODIFY  SWITCH_MODE  Switching_mode Nphase Off_1 Time_1 Weight_1
    Off_n Time_n Weight_n

    Change the description of the switching mode. This command is  typically
    used  for "foreign" data when this information has not been decoded cor-
    rectly by the conversion package.

    For each phase, one should specify:
      - the offset for the phase (in MHz for frequency switching, in current
        angular unit otherwise).
      - the duration of the phase (in seconds)
      - the weight given to phase (arbitrary units)
