Pitch angle model of sin^n form
Parameters: | omniflux : arraylike or float
order : integer or float (optional)
alphas : arraylike (optional)
|
---|---|
Returns: | dnflux : array
alphas : array
|
Notes
Directional number flux integrated over pitch angle from 0 to 90 degrees is a factor of 4*pi lower than omnidirectional number flux.
Examples
Omnidirectional number flux of [3000, 6000]
>>> from spacepy.empiricals import vampolaPA
>>> vampolaPA(3000, alpha=[45, 90])
(array([ 75.99088773, 151.98177546]), [45, 90])
>>> data, pas = vampolaPA([3000, 6000], alpha=[45, 90])
>>> pas
[45, 90]
>>> data
array([[ 75.99088773, 151.98177546],
[ 151.98177546, 303.96355093]])
