xpipe.tools.selector.matchdd

xpipe.tools.selector.matchdd(pars, refpars, win=None, wref=None, bins=30)[source]

Matches two D-dimensional distributions by reweighting individual objects

New weights are assigned by comparing the normalized, weighted histograms of the two datasets

Parameters

  • pars (np.ndarray) – data table to be reweighted, shape (N1, D)

  • refpars (np.ndarray) – reference data table, shape (N2, D)

  • win (np.array) – weights for the data table

  • wref (np.array) – weights for the reference table

  • bins (int or tuple) – number of bins, or tuple of bin edges

Returns

new weights for the input catalog

Return type

np.array
