spacepy.empiricals.getVampolaOrder

spacepy.empiricals.getVampolaOrder(L)[source]

Empirical lookup of power for sin^n pitch angle model from Vampola (1996)

Vampola, A.L. Outer zone energetic electron environment update, Final Report of ESA/ESTEC/WMA/P.O. 151351, ESA-ESTEC, Noordwijk, The Netherlands, 1996.

Parameters
Larraylike or float
Returns
orderarray

coefficient for sin^n model corresponding to McIlwain L (computed for OP77?)

Examples

Apply Vampola pitch angle model at L=[4, 6.6]

>>> from spacepy.empiricals import vampolaPA, getVampolaOrder
>>> order = getVampolaOrder([4,6.6])
>>> order
array([ 3.095 ,  1.6402])
>>> vampolaPA([3000, 3000], alpha=[45, 90], order=order)
(array([[ 140.08798878,  192.33572182],
    [ 409.49143136,  339.57417256]]), [45, 90])
