# spacepy.empiricals.getPlasmaPause

`spacepy.empiricals.``getPlasmaPause`(ticks, model='M2002', LT='all', omnivals=None)

  Plasmapause location model(s)

  CA1992 – Carpenter, D. L., and R. R. Anderson, An ISEE/whistler model of equatorial electron density in the magnetosphere, J. Geophys. Res., 97, 1097, 1992. M2002 – Moldwin, M. B., L. Downward, H. K. Rassoul, R. Amin, and R. R. Anderson, A new model of the location of the plasmapause: CRRES results, J. Geophys. Res., 107(A11), 1339, doi:10.1029/2001JA009211, 2002.

  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
