Utility functions for the reaction plane fit.

class reaction_plane_fit.base.FitType(region: str, orientation: str)

Bases: object

Describes the fit parameters of a particular component.

region

Describes the region in which the data for the fit originates. It should be either “signal” or “background” dominated.

orientation

Describe the reaction plane orientation of the data. For data which does not select or orientation, it should be described as “inclusive”. Otherwise, the values are up to the particular implementation. As an example, for three RP orientations, they are known as “in_plane”, “mid_plane”, and “out_of_plane”.

class reaction_plane_fit.base.ReactionPlaneParameter(orientation: str, phiS: float, c: float)

Bases: object

Parameters that defined a reaction plane.

orientation

Reaction plane orientation.

Type:str

phiS

Center of the reaction plane bin.

Type:float

c

Width of the reaction plane bin.

Type:float

reaction_plane_fit.base.component_fit_result_from_rp_fit_result(fit_result: pachyderm.fit.base.FitResult, component: fit.FitComponent) → pachyderm.fit.base.BaseFitResult

Create a component fit result from the fit component and the RP fit result.

Parameters:

• fit_result – Fit result from the RP fit.
• component – Fit component for this fit result.

Returns:

Constructed component fit result.

reaction_plane_fit.base.format_input_data(data: Union[Dict[str, Dict[str, Union[Any, pachyderm.histogram.Histogram1D]]], Dict[FitType, pachyderm.histogram.Histogram1D]]) → Dict[reaction_plane_fit.base.FitType, pachyderm.histogram.Histogram1D]

Convert input data into a more convenient format.

By using FitType, we can very easily check that all fit components have the appropriate data.

Parameters:data – Input data to be formatted. Returns:Properly formatted data, with FitType keys and histograms as values.
