config.PchipInterpolator2D

class config.PchipInterpolator2D(coords_data, values_data, pri, sec)

2D interpolation over PPPC4DMID raw data, using the PCHIP method.

Parameters:

coords_data : ndarray, size (M,N)

values_data : ndarray

pri : string

Specifies primary annihilation channel. See get_pppc_spec() for the full list.

sec : {‘elec’, ‘phot’}

Specifies which secondary spectrum to obtain (electrons/positrons or photons).

Notes

PCHIP stands for piecewise cubic hermite interpolating polynomial. This class was built to mimic the Mathematica interpolation of the PPPC4DMID data.

Attributes:

pri : string

Specifies primary annihilation channel. See get_pppc_spec() for the full list.

sec : {‘elec’, ‘phot’}

Specifies which secondary spectrum to obtain (electrons/positrons or photons).

get_val : function

Returns the interpolation value at (coord, value) based

Methods

__init__(coords_data, values_data, pri, sec)

Initialize self. See help(type(self)) for accurate signature.

Methods
