Windowed Multipole Library Format

/version (char[])

The format version of the file. The current version is "v1.0"

/nuclide/

  • broaden_poly (int[])

    If 1, Doppler broaden curve fit for window with corresponding index. If 0, do not.

  • curvefit (double[][][])

    Curve fit coefficients. Indexed by (reaction type, coefficient index, window index).

  • data (complex[][])

    Complex poles and residues. Each pole has a corresponding set of residues. For example, the i-th pole and corresponding residues are stored as

    data

    The residues are in the order: scattering, absorption, fission. Complex numbers are stored by forming a type with "r" and "i" identifiers, similar to how h5py does it.

  • E_max (double)

    Highest energy the windowed multipole part of the library is valid for.

  • E_min (double)

    Lowest energy the windowed multipole part of the library is valid for.

  • spacing (double)

    spacing

    Where data is the maximum energy the windows go up to. data is the minimum energy and equivalent to E_min, and data is the number of windows, given by windows.

  • sqrtAWR (double)

    Square root of the atomic weight ratio.

  • windows (int[][])

    The poles to start from and end at for each window. windows[i, 0] and windows[i, 1] are, respectively, the indexes (1-based) of the first and last pole in window i.
