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
