  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
