  Parameters
    ticks spacepy.time.Ticktock

      TickTock object of desired times

    Lpp_model string, optional

      ‘CA1992’ or ‘M2002’ (default) CA1992 returns the Carpenter and Anderson model, M2002 returns the Moldwin et al. model

    LT int, float

      requested local time sector, ‘all’ is valid option

    omnivals spacepy.datamodel.SpaceData, dict

      dict-like containing UTC (datetimes) and Kp keys

  Returns
    out float

      Plasmapause radius in Earth radii

  Warns
    RuntimeWarning

      If the CA1992 model is called with LT as it is not implemented
