- ess.reduce.polarization.he3.he3_opacity_function_from_beam_data(transmission_empty_glass, transmission_fraction, opacity0_initial_guess)[source]#
Opacity function for a given cell, based on direct beam data.
Note that this can alternatively be defined via cell parameters, see
he3_opacity_function_from_cell_opacity(). The cell opacity is used as an initial guess for the fit.- Return type:
He3OpacityFunction[TypeVar(PolarizingElement,polarization.types.Analyzer(str),polarization.types.Polarizer(str))]
