class openmc.data.SingleLevelBreitWignerCovariance(energy_min, energy_max, parameters, covariance, mpar, lcomp, file2res)[source]

Single-level Breit-Wigner resolved resonance formalism covariance data. Single-level Breit-Wigner resolved resonance data is is identified by LRF=1 in the ENDF-6 format.

Parameters

  • energy_min (float) – Minimum energy of the resolved resonance range in eV

  • energy_max (float) – Maximum energy of the resolved resonance range in eV

Variables

  • energy_min (float) – Minimum energy of the resolved resonance range in eV

  • energy_max (float) – Maximum energy of the resolved resonance range in eV

  • parameters (pandas.DataFrame) – Resonance parameters

  • covariance (numpy.array) – The covariance matrix contained within the ENDF evaluation

  • mpar (int) – Number of parameters in covariance matrix for each individual resonance

  • formalism (str) – String descriptor of formalism

  • lcomp (int) – Flag indicating format of the covariance matrix within the ENDF file

  • file2res (openmc.data.ResonanceRange object) – Corresponding resonance range with File 2 data.
