afw.common.DileptonMassToPlot#

class afw.common.DileptonMassToPlot(title: str, first_lepton_name: str, first_lepton_index: int, second_lepton_name: str, second_lepton_index: int)[source]#

Bases: ThingToPlot

Plot the dilepton mass of two leptons. The order doesn’t matter due to the cos and cosh functions being even.

No check is done to ensure the given lepton is present. Non-present leptons will result in a crash.

__init__(title: str, first_lepton_name: str, first_lepton_index: int, second_lepton_name: str, second_lepton_index: int)[source]#
Parameters:

  • title (str) – The title of the overall plot.

  • first_lepton_name (str) – The name of the first lepton. This should match a key in events.

  • first_lepton_index (int) – The index of the first lepton.

  • second_lepton_name (str) – The name of the second lepton. This should match a key in events.

  • second_lepton_index (int) – The index of the second lepton.

Methods

__init__(title, first_lepton_name, ...)

create_histogram()

Create a histogram for the given thing to plot.

fill_histogram(histogram, events, dataset, ...)

Fill a histogram with a given set of events, post-selection

plot_histogram(histogram, output_file)

Plot a filled histogram to a given file
create_histogram() → Hist[source]#

Create a histogram for the given thing to plot.

Returns:

A histogram.

Return type:

hist.Hist

fill_histogram(histogram: Hist, events: Array, dataset: str, weights: Array, **kwargs: dict[Array]) → Hist[source]#

Fill a histogram with a given set of events, post-selection

Parameters:

  • events (ak.Array) – Events post-selection

  • dataset (str) – The dataset for which the events belong

  • weights (ak.Array) – A one-dimensional array with the same length as events

Returns:

A histogram with filled data

Return type:

hist.Hist

plot_histogram(histogram: Hist, output_file: str) → None[source]#

Plot a filled histogram to a given file

Parameters:

  • histogram (hist.Hist) – The filled histogram to plot.

  • output_file (str) – The output file, given as an absolute path.

  • **kwargs (dict | None) – A set of keyword arguments created in by the analysis config.

Returns:

None
